each channel can have an alphanumeric label assigned to it so that operators can more
easily confirm they have the correct channel selected. The default use for the bottom line
of the display is a VU meter on the left side and a clock on the right. The VU meter gives
a real time indication of audio levels for both receive and transmit audio. The clock can be
configured to display in either the 12-hour or 24-hour format when the remote is set up.
The clock display can also be disabled for those dispatch centers using a central “master
clock” for logging their calls.
Function Tones
The operator should not hear any control/function tones being sent when he or she
operates any control on a Model 280 or 284, since the remote mutes its speaker or headset
audio while those tones are being sent. They should not hear any tones from parallel
remote equipment in the system either, since the remotes are programmed to recognize the
tones from other units and mute its receive audio until they are finished as well. The one
exception is that the operator will hear any Alert tones sent for as long as the function
button is held down. Parallel function tone muting may also be disabled, if desired.
The programmable features for the Digital Tone Remotes allow the installer to choose
whether the function tones for channel selection are sent when the key-press is made or
only after PTT is pressed. In the Model 280 and 284, the installer can also enable or
disable the masking of the function tones from other parallel remotes.
Power On
When power is first applied to the remote, it will display a message in the LCD window
similar to
Figure 2 .
Figure 2: Initial Power-On Screen
The top line identifies the remote and gives the version number of its installed software.
The lower line can have a 16 character label programmed into it to identify the system the
remote is setup for. After a few seconds delay the display will change to the one shown in
Figure 3 .
Figure 3: Retrieving Non-volatile Memory
The “configuring” display will remain for a few seconds, as the remote retrieves all of its
programmable operating parameters from nonvolatile memory. The hyphen (shown at the
