Low Voltage Threshold Warning; Wi-Fi; Turning Wi-Fi On Or Off - Motorola APX E5 User Manual

Whenever the radio goes off-hook, it changes to a preprogrammed zone channel assigned for off-hook
state. While in off-hook state, you can change the mode manually. When you return the radio to
on-hook state, it reverts to its previous channel zone before the radio goes off-hook.
NOTE: If the radio is operating on Tone Private Line (PL) Defeat or Suspend Scan operations
during on-hook state, the radio is converted to work in a new channel and the Channel Change
on Off-Hook feature is suspended until these conditions end.
During Dynamic Regroup channel selector lock state, Emergency, Transmit Inhibit, radio lock,
or when an external key loader is attached to the radio, the Channel Change on Off-Hook
feature is suspended until the following conditions end.
The Off-Hook State for APX Dual-Radio Setup
For Dual-Radio, the state of the Hub on the unselected radio is always considered as on-hook.
When the Hub is in off-hook state, the selected radio changes the channel according to the
configuration of the Customer Programming Software (CPS), and the unselected radio does not
trigger a channel change.
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.
NOTE: 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.
NOTE: 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.
