SECTION TWO
BEFORE BEGINNING
HOW VHF RADIOS WORK
The Humminbird DC5s hand-held radio is a VHF transceiver. This means that the radio has the
capability to both transmit signals as well as receive them, and operates in the VHF (very high
frequency) spectrum.
The marine band is a group of VHF frequencies between approximately 156 MHz and 163 MHz.
This band is divided into a number of discrete channels, which are numbered and further
categorized by use.
Within the marine band, 10 channels are designated for continuous weather broadcasts. These
channels are grouped into a “Weather Band” and designated “receive only” channels. You cannot
transmit on a weather channel.
The remaining frequencies are assigned for various purposes and given a channel number.
There are basically two different channel numbering and frequency assignment schedules
currently in use, which creates two different bands of frequencies: the USA band and the
International band. These two bands share the same frequencies but assign channel numbers
slightly differently, and allocate these channels for different uses.
A list of USA, International, and Weather bands including channel numbers, frequencies, and
descriptions of use is included in Section 6 of this manual.

back cover of this manual.
INSTALLING THE ANTENNA
The antenna supplied with your DC5s is specifically tuned to optimize the radio’s transmit power
and the sensitivity of the receiver. To install, ensure the threaded base and the recessed threads
on the unit are free from debris, and screw the antenna into the base. Finger tighten only.
INSTALLING THE BELT CLIP
The belt clip performs two purposes – it can be used to carry the DC5s from a belt or pocket,
and the rubber pad works in conjunction with the charger jack cover to provide a skid-proof
stance when the radio is laying on it’s back.
www.reelschematic.com
www.reelschematic.com
If you choose to use the belt clip included with your DC5s, simply fasten it to the mounting point
using the attached screw. A flat head screwdriver or a small coin can be used. Do not over
tighten the screw or use a fastener other than the one supplied.
BATTERY REMOVAL AND INSTALLATION
The battery pack is pre-installed on your DC5s. It is not necessary to remove it for charging or
normal operation. If you are using more than one battery pack you can remove the battery pack
by simply sliding it off the DC5s unit. Some force may be necessary to overcome the mechanical
detent.
www.reelschematic.com
www.reelschematic.com
When the battery pack is off the DC5s unit, care should be used to prevent damage to the
mating slide and electrical contacts on the top of the battery. Also the slide and contact area on
the bottom of the unit will be vulnerable to damage if not protected. It is best to keep the battery
pack installed even if the radio is being stored for extended periods.
BATTERY CHARGING
The battery pack included with your DC5s contains Nickel-Cadmium type rechargeable
batteries. Battery charge life (how long the battery will hold a charge) varies with a number of
factors including temperature, frequency of use, use of the transmitter, etc.
Nickel Cadmium batteries are used due to their long operational life. Proper use of your NiCd
batteries will extend both the charge life and the battery life.
NiCd batteries require regular exercises in order to maintain their full potential. A battery that is
kept at full charge continually, by charging over a long period of time (30 days) will develop a
memory effect which considerably shortens the charge life. A more common type of memory
effect is induced by uniform shallow cycling. For example, if a battery is repeatedly operated at
50% of its full capacity.
Ideally, a NiCd battery should be fully charged, fully depleted, fully charged, etc. This exercising
prevents the memory effect and ensures maximum charge life of the battery.
If a battery shows early signs of reduced charge life due to the memory effect, it is easy to
restore the battery to it’s full potential by intentionally exercising the battery several cycles from
full charge to full discharge.
The battery pack can be charged on or off the DC5s unit. Both the 110 VAC adapter and 12
VDC cigarette lighter adapter (available as an accessory) will power the DC5s for normal
operation while maintaining a trickle charge to the battery pack.
Additionally, a 1-hour quick charger is available as an accessory which enables very fast change
cycles from a 110 VAC source.
If the DC5s is used frequently or for an emergency, a back-up battery pack is a good idea.
Before using your DC5s for the first time, the battery should be fully charged. To charge the
DC5s battery, simply plug the charger into the charge jack on the rear of the battery pack. If you
are using the wall charger, the red LED light will illuminate if proper connection is made and the
battery is accepting the charge. When possible, charge the battery at room temperature. Never
charge the battery below 50 degrees F (10 degree C) or above 95 degrees F (35 degrees C)
since this could cause damage to the battery or reduce the charge life.
www.reelschematic.com
www.reelschematic.com
The battery drain is considerably greater when transmitting than receiving. A battery charge can
be maintained for 8 hours or more (depending on ambient temperatures) when receiving only.
Frequent transmitting, especially on High (5 Watt) output power will significantly increase the
battery drain.
The battery will be fully discharged within one month even with power off.
Note: The nickel-cadmium (NiCd) battery contained in the DC5s battery pack must be recycled
or disposed of in an environmentally sound manner. Do not place batteries in your regular trash.
The incineration, land filling or mixing of nickel-cadmium batteries with the municipal solid waste
stream is prohibited by law in some areas. Incineration may cause an explosion. Return the
battery to a federal or state approved nickel –cadmium battery recycler,
Contact your local waste management officials for additional information regarding the
environmentally sound collection, recycling and disposal of this battery or call Humminbird at the
Customer Support number listed inside the rear cover of this manual.
SECTION FOUR
CONTROL FUNCTIONS
-
Control of the DC5s are divided into three functional areas:
The Power/Volume and Squelch controls are located on the top of the radio.
The PTT (push to talk) switch is located on the side of the radio.
The function control keys are located on the front of the radio.
www.reelschematic.com
www.reelschematic.com
Most control inputs result in audible, tactile, and visual feedback for positive actuation in loud
environments.
POWER AND VOLUME CONTROLS
To power the DC5s for operation, turn the Power/Volume knob clockwise past the detent. The
display will illuminate indicating that power is supplied to the DC5s unit. Continue turning the
Volume knob until the desired audio volume is achieved. It may be necessary to adjust the
squelch first, then adjust the volume once a transmission is received.
To turn the DC5s off, turn the Power/Volume knob counter- clockwise until the detent is felt and
the display is blank.
ADJUSTING THE SQUELCH
The squelch is commonly used to eliminate static and background noise from being heard. To
adjust the squelch, ensure that the unit is powered and sufficient volume is available to hear the
speaker. Turn the Squelch knob counter-clockwise as far as it will go. Adjust the volume to the
desired level. Wait for a period when no transmission is being received, and turn the Squelch
slowly clockwise until the background static is eliminated.
The squelch allows silent operation of the DC5s until a transmission is received. If the Squelch
is adjusted too high, only the strongest transmissions will be heard. If the Squelch is adjusted too
low, intermittent static and noise will be heard.
USING THE PTT
The Push To-Talk switch is located on the side of the DC5s and is easily accessible to both left
and right hand users. To activate the PTT, simply press the raised portion of the switch. A tactile
www.reelschematic.com
www.reelschematic.com
click will be felt, and the display will show the TX (transmit) symbol indicating that the unit is
transmitting.
Care should be used to prevent the inadvertent actuation of the PTT switch. When storing the
radio while powered, ensure that nothing comes into contact with the PTT. Inadvertent actuation
will transmit a signal causing interference with other users, possibly interfering with an emergency
broadcast, and will quickly drain the battery as well.
SELECTING THE BAND
Upon power-up, the last selected band will be in operation. The band, USA, INT (International),
or WX (weather) is indicated on the display.
Pressing the BAND button will toggle between these three bands. As with all controls, an
audible chirp will be heard when the button is pressed.
SELECTING THE CHANNEL
Within each of these three bands there are a number of discrete channels. These channels are
selected using the UP and DOWN arrow keys. Pressing either key once will select the next higher
or lower channel. Pressing and holding either arrow key will scroll through all available channels.
USING DUAL WATCH
Channel 16 is the normal monitoring channel for all maritime applications. In some instances,
the government mandates continuous monitoring of channel 16. Dual watch is a useful feature
that allows you to monitor channel 16 and another channel of your choice simultaneously.
www.reelschematic.com
www.reelschematic.com
Select any channel on either USA or INT bands. Press DUAL. The DC5s will monitor your
selected channel and channel 16 simultaneously. If a transmission is heard on either channel,
that channel will continue to be selected until no further transmission is received, then dual watch
will be re-engaged.
When using Dual Watch, the DC5s will also monitor the active WX channel for a special alert
tone issued during times of severe weather. You must select an active WX channel prior to
entering Dual Watch for this feature to work. Should this tone be received, the DC5s will emit an
alarm tone. Pressing the BAND button will switch the broadcast to the weather channel. Pressing
BAND again will exit the WX channel and you may enter Dual Watch again. You cannot enter
Dual Watch from the WX channel.
Pressing DUAL a second time will disable Dual watch.
Pressing the PTT button will also disable Dual watch. Pressing the PTT button a second time
will allow transmission.
USING SCAN
Scan is the sequential monitoring of all channels within the selected band. Pressing SCAN will
cause the DC5s to briefly monitor each channel starting with the current channel, and if no
transmission is heard, move to the next higher channel. If while monitoring a channel a
transmission is heard, the DC5s will remain on that channel until it is clear, then move to the next
channel.
Pressing the SCAN button again will disengage scan.
Pressing the PTT button will also disable scan. Pressing the PTT button a second time will allow
transmission.
USING THE CHANNEL 16 QUICK SELECT
www.reelschematic.com
www.reelschematic.com
Channel 16 is the standard channel for an emergency broadcast. The 16 button selects channel
16 quickly from any other channel or band. If the WX band is currently in use, channel 16 on the
USA band is selected. If you are using the DC5s on the INT band when 16 is selected, channel
16 of the INT band is selected.
Channel 16 represents the same frequency on both USA and INT bands.
If 16 is pressed again, the DC5s will return to the previously selected channel.
USING MEMORY
The DC5s is capable of storing up to 10 frequently used channels from either USA or INT
bands. Memory acts as its own band, so that you can scan between memory channels. Weather
channels cannot be stored in memory.
The Memory function consists of two buttons. M+/- and MEM. To store a channel to Memory,
first select that channel, then press M+/-. The MEM enunciator will appear on the display for a
second indicating that the currently selected channel has been stored to Memory. Continue this
procedure for all the frequently used channels you wish to store into memory.
By pressing MEM, the Memory function is selected and the MEM enunciator will be continuously
displayed. When in the MEM function, only channels stored to Memory will be accessible. The Up
and Down arrow keys can be used to select any channel stored to memory. SCAN can be used
to scan only the Memory channels.
At least one channel must be stored in memory in order to access the Memory function.
Pressing MEM when in Memory will return the unit to the previously selected band and channel.
www.reelschematic.com
www.reelschematic.com
To delete a channel from Memory, select the Memory function and ensure the MEM enunciator
is displayed. Use the Up or Down arrow button to select the channel to be deleted, and press
M+/-. The channel is now deleted from memory.
Remember, you must be outside of the Memory function to store a channel to Memory, and the
Memory function must be active to delete a channel from Memory.
Note: Removing the battery pack will erase programmed channels from memory. Programmed
channels may also be lost if the battery charge is low.
USING THE BACKLIGHT
The LIGHT button turns on the backlight for both the display a and the keypad. Pressing the
LIGHT button again will turn the backlight off or, if no button is pressed, the light will go off
automatically after about 10 seconds in order to save battery power.
SELECTING TRANSMIT POWER
The DC5s has a selectable transmit power output. The HI annunciator indicates that the unit will
transmit at 5 watts, the LO annunciator indicates the 1 watt output power is selected. Press HI/LO
to toggle between the two.
Selection of certain channels will cause the DC5s to automatically select the LO power output.
This feature is required by the FCC.
The HI power output will usually result in greater transmit range, at the expense of battery
consumption. When maximum range is not necessary, selecting LO transmit power will conserve
battery power.
SECTION FIVE
OPERATION
USING THE DC5s
To place a call with the DC5s, turn the power on and adjust the volume and squelch controls.
Use the Up and Down arrow buttons to select the desired channel. Normally, channel 16 is used
for an initial call, then once contact is made with the receiving party, another channel is selected
by both parties to avoid excessive congestion on channel 16.
www.reelschematic.com
www.reelschematic.com
Before transmitting, listen for activity on your channel. Do not interrupt another user.
Press the PTT button to transmit. Pause briefly then speak at a normal volume while holding the
DC5s unit 4-5” from your mouth. Speak directly into the speaker/microphone area. Greatest
range will be achieved when the radio is held vertically, and standing clear of obstructions which
may block the transmitted signal.
Refer to the FCC Rules and Regulations Part 80 for proper VHF radiotelephone procedures and
terminology.
SECTION SIX
SAFETY AND MAINTENANCE
MAINTENANCE
Your Humminbird DC5s radio is designed to provide years of trouble-free operation with virtually
no maintenance. Follow the simple procedures listed below to ensure your DC5s continues to
deliver top performance.
If the DC5s comes into contact with salt spray, simply rinse the unit off with fresh water and a
clean cloth.
When cleaning the protective clear lens, use a non-abrasive cleaner such as mild soap and
water. Avoid using alcohol based glass cleaners as this may weaken the material and cause it to
fail.
Never transmit with the antenna removed from the unit, as this will damage the transmit circuit of
the unit.
Do not remove the housing fasteners or attempt to make repairs to the radio yourself. The case
is sealed to prevent water intrusion and special tools are required for reassembly. Repairs should
be performed by authorized Humminbird technicians only.
Periodically exercise the battery from full charge to fully drained. Keeping the battery continually
at full charge will create a memory effect which reduces the charge life.
www.reelschematic.com
www.reelschematic.com
The battery pack contains Nickel-Cadmium batteries. Use care not to damage the outer case,
and if the battery is no longer operable, dispose of properly. See “Battery Removal and
Installation” section for additional disposal information or call Humminbird’s Customer Support
number listed inside the rear cover of this manual.
Note: Do not dispose of any battery in a fire because it may explode!
SAFETY AND MAINTENANCE
Never leave this or any electronic device in a closed car or trunk – the extremely high
temperatures generated in hot weather can damage temperature sensitive components.
TROUBLESHOOTING
1. The screen begins to fade out. Images on the screen are not as sharp and clear as usual.
Check your battery to see that it is fully charged.
2. Low level or no sound comes from the speaker.
Adjust the VOLUME and SQUELCH knobs as described in Section Four.
3. Sensitivity is low, and only strong signals are audible.
Check the antenna connector for salt spray or dirt. Make sure he antenna connector is properly
seated.
4. The battery only lasts a short period of time.
Restore the full charge capability of the battery by exercising the battery from fully charged to fully
depleted. This exercising prevents the memory effect and ensures maximum charge of the
battery.
