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 f ew seco nds.
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.

Beltpac or All-In-One Headset Adjustments
Sidetone Adjustment (Beltpac only, not on all-in-one headset)
When you speak into the microphone, you can hear sidetone (your own voice) in the beltpac headset.
Sidetone can be adjusted as follows:
1 Be sure the beltpac power is on. 2 While holding down the “O” button, press the volume-up ▲ or volume-down
▼ button as many times as needed to reach an acceptable level. You do not hear beeps except for maximum or minimum double beep. Maximum sidetone level is recommended.
Microphone Gain Adjustment
Some people speak louder or softer than average. The microphone gain adjustment helps to compensate for extremes in speaking level of individuals using beltpacs or all-in-one headsets.
NOTE: The microphone gain can be monitored through sidetone, or preferably by
someone else using a beltpac or all-in-one headset, or at the base station.
1 Be sure the beltpac or all-in-one headset power is on. 2 While holding down the “X” button, press the volume-up ▲ or volume-
down ▼ button as many times as needed to reach an acceptable level. You do not hear beeps except for maximum or minimum double beep. Recommended microphone gain levels are: Beltpacs – 12 clicks down from maximum All-in-one headsets – 8 clicks down from maximum
NOTE: You will hear “Maximum” if you try to go above maximum microphone gain.
You will hear repeating beeps if you try to go below minimum microphone gain. Microphone gain and sidetone adjustments will be saved in memory and do not need to be reset after the unit is turned off and on.

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-of-
sight 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!
