Preparing the Handset for Use
To prepare the handset for use:
1. Insert two AAA batteries into the battery compartment.
2. Set the handset DIP switch positions 6 and 7 to OFF and position 8 to ON.
3. Turn the power switch off and back on to ensure the DIP switch changes
take effect.
DIP Switch Settings for the Handset
While DIP switch positions 6 through 8 affect the handset and base station settings, DIP switch
positions 1 through 5 are used to set the radio frequency channel used for communication between
the handset and the base station.
Selecting the Radio Frequency Channel
There are two ways to configure the radio frequency (RF) channel spacing. The first method reduces
channel-to-channel interference, but allows only 12 channels to operate simultaneously in the same
vicinity. The second method increases the number of channels that can be used simultaneously to 20
channels. However, this method diminishes the channel-to-channel noise immunity.
All of the WVL pairs in the same vicinity must use channels from RF Channel Group 1 or RF Channel
Group 2, and channels must belong to the same group. The DIP switch determines the initial
communication frequencies that the WVL pair use to communicate when the power of the base station
and handset is first turned on. If there is too much interference at the initial channel, the WVL pair
changes frequency automatically and continues operating. The WVL pair repeats this process
automatically as needed and changes frequencies when interference is too high.
Multiple WVL pairs can be set to the same initial frequency. However, setting different initial
frequencies helps the WVL pairs quickly find a stable operating frequency.
For example, if there are 12 or fewer simulators in the same vicinity, set all of the WVL pairs to use
channel 0 of RF Channel Group 1. To give unique initial RF frequencies, assign each WVL pair to its own
RF channel with the settings found in CH 0 through CH 11.
