Spectrum Friendly™ Interference Avoidance
Most Wi-Fi access points allow the administrator to set the channel and bandwidth for the system. Some systems employ
an “Auto” mode, in which the Wi-Fi access point will automatically select the channel.
With Wi-Fi access points, it is sometimes advantageous to manually select a channel number to keep the Wi-Fi
transmission at a xed location. Common Wi-Fi channels used are 1 and 11.
To avoid the Radio Frequency interference caused by Wi-Fi routers and Wi-Fi access points, the DX340|HD Base
Station offers three user selectable Hop Bands of radio operation. Making use of these bands can assure that base
communication is always free of interference.
Interference may be characterized as mechanical sounding voices; voices breaking up while talking; or hearing a “Busy”
prompt in the headset when a button is pressed.
All Band
When the DX340|HD is congured in All Band, the Base Station uses the entire broadcast frequency range, offering the
greatest opportunity for headsets to communicate with the base. Base Stations are shipped in the “A” position, which is
the default setting. However, when in All Band, the base can be susceptible to interference from Wi-Fi routers and Wi-Fi
access points. To avoid this interference, the DX340|HD offers two other bands: Low and High.
Low Band
Using Low Band sets the frequency range in which the Base Station operates to the lower end of the broadcast range. If
you know that the Wi-Fi access point is set to Wi-Fi channel 11, then you should set the base station to operate in “Low”
band so the base avoids the Wi-Fi channel 11 frequency range.
High Band
Using High Band sets the frequency range in which the Base Station operates to the upper end of the broadcast range. If
you know that the Wi-Fi access point is set to channel 1, then you should set the base station to operate in “High” band so
the base avoids the Wi-Fi channel 1 frequency range.
A Base Station’s frequency band setting can be changed 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, then simultaneously press and hold
the REGISTER button.
The STATUS window will show L, H, A or E (Europe).
3 Press the CLEAR/BAND button repeatedly to cycle through the frequency band:
L = Low end, H = High end, A = All and E = Europe.
Stop at the desired setting and wait until “c” appears on the STATUS display.
NOTE:
Base stations are shipped in the “A” (default) position.
The letter “c” will only appear on the STATUS display if you are setting the frequency band the rst
time or if you are changing the setting.
If you stop at L, H, A or E that was previously set, an “8” will appear for a few seconds and the
STATUS display will turn blank.
If you change a base station’s existing frequency band setting, you will have to re-register all beltpacs
that were registered to that base station.

Beltpac Adjustments
Sidetone Adjustment
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. If you reach the high limit, you will hear “maximum” in the headset. If you reach the low
limit, you will hear double beeps.
Maximum sidetone level is recommended.
Microphone Gain Adjustment
Some users speak louder or softer than average.
The microphone gain adjustment helps to compensate for extremes in speaking level of coaches using beltpacs.
NOTE: The microphone gain can be monitored through sidetone, at the base station or preferably
by someone else using a beltpac.
1 Be sure the beltpac power is turned 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. If you reach the high limit, you will hear “maximum” in the headset. If you reach the low
limit, you will hear double beeps.
Recommended microphone gain levels are:
• Beltpacs – 12 presses down from maximum.
NOTE: Microphone gain and sidetone adjustments will be saved in memory. A reset is not
required when the unit is turned off and on.
