Spectrum Friendly™ Interference Avoidance
Interference such as popping sounds may occur when frequencies of a WiFi
system, a wireless DMX lighting system or another HME system is in use.
This interference may be avoided if these systems can be limited to one
portion of the 2.4GHz to 2.48GHz frequency band, and your base station is set
to operate in the opposite half of the band as follows:
1
Turn the base station power on.
The STATUS window will show “8” for a few seconds.
After the “8” disappears, the
STATUS window will be blank.
2
Press and hold the CLEAR/BAND button and, while you are still holding
the CLEAR/BAND button, press and hold the REGISTER button.
When the STATUS window shows L, H or A,
release both buttons.
3
Press the CLEAR/BAND button repeatedly to cycle through parts of the
frequency band ― L = Low end, H = High end and A = All
Stop at the desired setting and wait until “c” appears
on the STATUS display.
NOTE: Base stations are shipped in the “A” (default) position.
“c” will appear on the STATUS display if you are re-setting the frequency band.
If you change a base station’s existing frequency band setting, you will have to
re-register all beltpacs and/or all-in-one headsets that were registered to that
base station.

When trying to register a beltpac or all-in-one headset, you hear “registration failed.”
Press the RESET button on the base station with the point of a pen.
The STATUS window will show “8” and then become blank.
Try again to register the beltpac or all-in-one headset.
If registration fails again, call your dealer for assistance.
No one can hear me when I talk.
On the beltpac or all-in-one headset, be sure you are pressing the X, O or ALL button.
On the base station, be sure you have selected the correct channel, and you are pressing the
TALK button.
Be sure the headset plug is properly connected to the beltpac or base station.
With more than one base station, one base station operator can not hear O or ALL
transmission from another base, or another base station operator can not hear X or
ALL transmission from another base.
Be sure interface cable is properly connected from BASE OUT on the primary base station to
BASE IN on the secondary base station, and so on.
If problem is not resolved, try using a different interface cable.
No or low auxiliary audio sound.
Check wiring from auxiliary equipment to AUX AUDIO connector on back of the base station.
Turn AUX AUDIO adjustments on front of base station with a small standard (flat) screw
driver, clockwise to increase level and counterclockwise to decrease level.

Beltpac or all-in-one headset users can not hear or talk to base station operators who
are using headsets.
Be sure base station headsets are fully plugged into the base station headset connectors.
Be sure the appropriate SELECT lights are red (O, X or ALL) when base station operators are
talking.
Be sure everyone is talking or listening on the right channel (O, X or ALL).
Beltpac range is bad.
Be sure antennas are properly connected and tightened on base station.
Be sure base station is positioned where there are no physical obstructions blocking line-ofsight from the base station to beltpacs or all-in-one headsets.
Beeping is heard in base station headset and SELECT lights are blinking.
Base station is operating on battery power and battery is low.
Not all beltpac buttons are working.
Button functions may have been changed to work in the desired operating mode
(See page 22).
There is interference from a cordless telephone.
A 2400MHz cordless telephone nearby may cause interference, which may be corrected by
doing the following:
Change frequencies on the phone.
Move the phone as far as possible from the base station.
Use another type phone.
(If your base station does not have a battery backup)
In the event of an electrical power outage — such as from lightning or a power generator
failure, if you experience problems with your DX300ES equipment after the power comes on
again, unplug the AC power supply from its electrical outlet and wait 15 seconds, then plug it
back in.

FREQUENTLY ASKED QUESTIONS
Are the battery charger and base station power supplies interchangeable?
Yes.
What is the maximum recommended number of base stations that can be linked
together with interconnect cables?
Four.
Does linking the base stations automatically prevent them from interfering with each
other?
No, all bases that are linked together must be initialized or set to the high or low portion of the
frequency band to prevent them from interfering with each other’s frequencies.
If the primary base station is turned off just momentarily (before the secondary base(s)
have a chance to start working independently), will the secondary base(s) automatically
re-initialize to the primary?
Yes, the secondary base(s) will re-establish communication without being initialized again.
Will a secondary base station continue to operate if its primary is turned off for a period
of time?
Yes & No. Secondary base stations will initially stop operating when the primary base is
turned off, but will resume operation independently after about 40 seconds.
Three bars will appear in its STATUS display, and its beltpacs will still be able to communicate.
If the primary base station is turned back on, the secondary base must be turned off and on
again to re-establish proper initialization.
Can I use more than three beltpacs on a single base station in dual channel mode?
Yes, but only three users will be able to transmit at the same time.
Up to 15 beltpacs can be registered to a single base station.
Beltpacs and all-in-one headsets should be placed in push-to-talk (PTT) mode when more than
3 beltpacs or all-in-one headsets are used (See page 22).
What should I do if my carrying case and equipment get wet?
Dry them out thoroughly before further use.
Be sure all equipment is dry before using it again.
CAUTION: Plugging wet electrical equipment into an AC power outlet is dangerous!
