User's Guide

With Channel Change on Off-Hook enabled, when the Hub is placed off-hook and radio switch
happens, the new selected radio moves to the target channel zone of its off-hook state. The new
unselected radio reverts to the last user selected channel before the off-hook state.
The Off-Hook State for Multiple Radios Setup
When multiple control heads are connected, the states of these Hubs reflect the state of the active
control head(s). Any Hub placed off-hook by the active control head(s) makes the radio goes into
off-hook state. The radio can be in on-hook state only when all Hubs are placed on-hook.
NOTICE: Familiarize yourself with the functionality of this feature as removing the microphone
easily triggers a mode change on the radio.

Low Voltage Threshold Warning
A specific external device is attached to the radio to monitor the automobile voltage. When the car
battery went lower than a pre-defined threshold, the external device asserts the Vehicular Interface
Port (VIP) input to the radio.
When the VIP switch turns on, the VIP asserts input to the radio. The radio immediately initiates a 15
seconds of low Voltage Pre-alert Timer. If the status of the VIP changed before this time-out timer
ends, the radio returns to normal operation.
If the status from the VIP remains unchanged when the time-out timer ends, the radio shows Low
Battery message on the display and low alert tone. The radio sounds a high-pitched tone immediately
after the PTT button is released.
NOTICE: If the mobile radio does not have a control head connected, the bricks can only alert
the user with battery alert tone and the transmit chirp.
