fails. If you attempt to power down the radio in the active Ambience Listening call, the radio enters Pseudo Power-
Off state.

Pseudo Power-Off

If you attempt to power down the radio in the active Ambience Listening call, the radio appears to turn off. However,
it remains fully operational from Layer–3 and below. The radio has a blank screen, and all LEDs are turned off.
When the AL call ends in this pseudo power-off state, the radio automatically turns off.
If you attempt to power up the radio from the pseudo power-off state, the radio acts as if it is really powering up.

Auto Power-On

The radio can be configured to turn on automatically after inserting the battery. This functionality is configurable
using CPS.
If the emergency mode was active before removing the battery, the radio enters this mode when the power-off period
is shorter than approximately 3 seconds. This behavior applies to normal and silent emergency modes. The three-
second period is approximate and determined by the discharge rate of capacitors in the radio. The period may last
from 3 up to 6 seconds.

Preemptive Priority Call

If during a call, a call setup is received for a call with higher priority than the present call, and the new call priority is
Preemptive Priority 3 (value 14 in the codeplug) or Preemptive Priority 4 – Emergency (15), the radio disconnects
from the present call and joins the new high priority call.
If the call priority of the new call is Preemptive Priority 1 (12) or Preemptive Priority 2 (13), depending on
configuration the radio either accepts or rejects the new call.
When the new call is accepted, a special tone is played, and you are notified of the high priority call.
When you initiate a private call and you receive a rejection with the reason Called party busy, you have the option to
interrupt the existing call or initiate a new call. However, this time the call is initiated with the preemptive priority.

Transmit Inhibit Mode

The Transmit Inhibit Mode is a mode in which the radio sends no radio transmissions. It is recommended to activate
the mode in RF sensitive areas, for example hospitals, airplanes, where safety can be jeopardized due to transmission
radiation.
To activate, select M
ENU
In this mode, the radio does not transmit under any circumstances except for the Emergency Calls. All the functions
and keys which cause transmission, for example registration to the network, changing talkgroup or folder, sending
SDS messages, or pressing the PTT button are disabled. Any transmission trial causes the radio to display Not
Allowed In TXI Mode notification and to play a tone.
Your radio can still receive:
• Group calls.
• Messages — stored in the Inbox.
• Private call attempts — stored in the Missed Calls list, without the option to respond.
When no danger to safety exists anymore (for example, you leave the RF sensitive area), you can deactivate the
Transmit Inhibit Mode and the radio returns to standard operation.
You can deactivate the mode by selecting M
One-Touch button, or implicitly when initiating an Emergency Call.
