Channel Change on Off-Hook
This feature determines the mode of the radio based on the Hub on or off-hook state of all the control
heads.
Whenever the radio goes off-hook, it changes to a programmed 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. 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.
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. If
the Hub is in off-hook state, the selected radio changes the channel according to the configuration
of the Customer Programming Software (CPS). 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
If multiple control heads are connected, the Hubs reflect the state of the active control heads. Any
Hub placed off-hook by the active control heads 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 can
easily trigger a mode change on the radio.

Selecting the Power Level
This feature enables you to select the power level at which your radio transmits. The radio always turns
on to the default setting. Power level Low enables a shorter transmitting distance to conserve power.
Power level High enables a longer transmitting distance.
Prerequisites: This feature must be programmed by a qualified radio technician.
Procedure:
Press the Pwr menu item.
If the power level is set to high, the display shows High power and the Power Level High icon.
