Adjusting the Volume

You may control the volume level using the

Radio On-

Off/Volume Control knob. After the radio is powered on, rotate the knob clockwise to increase the volume, or counterclockwise to decrease the volume.

Selecting a Channel

The radio supports up to 16 channels. Rotate the

Channel

Selector knob to align your desired channel number with the white channel mark.

To receive, just release the PTT. When any audio signal is received, the LED solidly glows green.

Note:

● To ensure optimal volume of the receiving radio, hold the radio approximately 2.5 to 5 centimeters away from your mouth.

●

Communication range may get affected in rainy days or forest locations.

Functions and Operations

CTCSS/CDCSS

You may set up talkgroups with unique CDCSS/CTCSS to prevent unwanted conversations at the same frequency.

If CTCSS/CDCSS is set on a certain channel, you can only receive voice calls from radios with matching CTCSS/

CDCSS. Otherwise you will receive voice calls from all users operating at the same frequency.

You may request your dealer to program corresponding parameters on certain channels. For detailed operation method, please consult your dealer.

Note:The radio supports 38 groups of standard

CTCSS, 83 groups of standard CDCSS, and 180 degree CTCSS tail reverse.

Time-out Timer (TOT)

The purpose of TOT is to prevent any user from occupying a channel for an extended period. If the preset time expires, the radio will automatically terminate transmission and keep beeping. To stop beeping, please release the PTT key. You must wait for a certain time period (preset by your dealer) before you can press and hold down the PTT key to transmit again.

If the pre-alert function is set by your dealer, your radio will alert you to the TOT expiration in advance.

Monitor

This feature allows you to lower the conditions for incoming signal match.

Operation:

■ Press the programmed Monitor key to activate this function (an alert tone sounds); press it again to deactivate the function (the alert tone sounds twice). Or

■

Press and hold the programmed Monitor Momentary key to activate this function (an alert tone sounds); release the key to exit (the alert tone sounds twice).

Squelch Off

This feature allows you to unmute the speaker on current channel, no matter whether a carrier is present.

9

Functions and Operations

Operation:

■ Press the programmed Squelch Off key to activate this function; press the key again to deactivate it. Or

■ Press and hold the programmed

Squelch Off

Momentary key to activate this function; release the key to deactivate it.

Note:When this function is enabled on current channel, you will hear audio signals (if any); otherwise, background noise will be heard.

Scan

This feature allows you to listen to communication activities on other channels so that you can keep a close track of your team members. The scan list can be set by your dealer.

Operation:

1. To activate this function, you may

■

Press the programmed

Scan key; or

■

Switch to a channel enabled with the auto scan feature

(programmed by your dealer).

10

Note: The radio will not start scan if there are less than two channels in the scan list.

2. After the feature is enabled, your radio will scan according to the scan list set for the channel on which scanning starts. The scanning process is as follows:

■

During scanning, the LED flashes green;

■ When communication activities are detected on a channel, the radio will stay to receive activities present on this channel. At this time, the LED glows green;

■ If the talk back feature is enabled by your dealer, press and hold down the PTT to reply when the radio stays on a certain channel.

■

You can scan the frequently used channel if the priority scan feature is enabled. When scan stays on a nonpriority channel, the radio will keep detecting activities on the priority channel. Once any activity is detected, it will jump to the priority channel. For more information, please consult your dealer.

Functions and Operations

3. To exit the scanning process, you may

■

Press the Scan key again; or

■ Switch to a channel where the auto scan feature is not enabled;

■ Turn the radio off.

Note:

●

You can enable or disable the following alert tones: scan start alert and scan exit alert.

● During scanning, the following function keys, if programmed, are available: PTT, .Squelch Off,

Squelch Off Momentary, Monitor and Monitor

Momentary.

VOX

This feature allows you to transmit the voice with no need to press PTT. However, you must employ a dedicated earpiece to realize this function.

Operation:

1. Set the PTT/VOX Switch on the earpiece to VOX;

2. Plug the earpiece into the accessory jack;

3. Press the programmed VOX key to activate this function;

4. Speak into the microphone (on the earpiece) to transmit your voice, and transmission will stop automatically when you stop talking;

5. Power the radio off or press the VOX key again to deactivate this function.

Note:

● If the PTT/VOX Switch on the earpiece is set to PTT, you can only transmit by pressing the external PTT, no matter whether VOX is activated.

● When the earpiece is plugged into the accessory jack, do not switch the

PTT/VOX

Switch from PTT to VOX directly if it is set to PTT; otherwise, continuous transmission may occur. If continuous transmission occurs unexpectedly, you can restore the radio to normal operation by toggling the switch from

VOX to PTT, or turning the radio off and back on.

11

Functions and Operations

● You can select an appropriate VOX sensitivity according to the operating environment. If VOX is activated under heavy noise, continuously transmission may occur.

Battery Strength Indicator

With this feature, you can learn the remaining battery strength easily.

Operation:

Press and hold down the programmed

Battery Strength

Indicator key, and the LED glows to indicate remaining battery strength by different colors (see table below). Release the key to exit. The table lists different colors representing different battery strength levels.

LED Indicator

LED glows green.

Low Battery Alert

This feature allows you to know the low battery status.

When battery power runs low, the LED will flash red, and the low-pitched tone (programmed by your dealer) will sound periodically. In this case, please replace or charge the battery.

Note: When the battery strength is insufficient, the programmed Battery Strength Indicator key will become unavailable. However, when the battery strength is drained, transmission will be prohibited; if you press PTT in such situations, the radio will sound an alert to warn you.

Channel Lock

This feature can avoid unexpected channel change due to rotation of Channel Selector knob by accident.

Operation:

Press the programmed Channel Lock to activate this function

(an alert tone sounds); press the key again to deactivate it

(the alert tone sounds twice). After this function is activated, the radio will stay on current channel; at this time, you can not change the channel even using the Channel Selector knob.

12

Functions and Operations

Note: This function will be deactivated if the radio is powered off and back on, or it is programmed.

Battery Save

In Standby mode, if the radio is inactive (no key press/ transmission/reception) for 10 seconds (programmable), it will automatically enter Battery Save mode to reduce battery consumption. The radio may exit the Battery Save mode and get activated once any key is pressed or any signal is received.

Busy Channel Lockout

If enabled via the programming software, this feature can prevent your radio interfering with other transmitting radios on the same channel. If you hold down the PTT key while the channel is in use, your radio will keep beeping and return to

Receive mode. To stop beeping, please release the PTT key.
