channel on which it was disabled, even after a power cycle. It may be required to return the radio

to the site in which it was disabled before it can receive an enable command over the air. This may

also be accomplished by communicating with the radio on the talkaround frequency of the site in

which it was disabled. The Radio Disable feature can be used to stop any inappropriate use of a

radio, or to prevent a stolen radio from functioning.

In MOTOTRBO systems, Radio Disable is configured in the portable and mobile radios with the

CPS. To allow a radio to use this function, it must be enabled in the CPS “Menu” settings. To

permit (or prevent) a radio from receiving and responding to this command, go to the “Signaling

Systems” settings in the CPS.

2.3.2.3 Remote Monitor

The Remote Monitor feature allows a remote user to activate a target radio’s microphone and

transmitter for a period of time. A call is silently set up on the target radio, and its PTT is controlled

remotely without any indications given to the end user. The duration that the target radio transmits

after receiving a Remote Monitor command is set in the target radio through the CPS. When

receiving the Remote Monitor command, the target radio initiates a Private Call back to the

originator of the Remote Monitor command.

This feature is used to ascertain the situation of a target radio which is powered-on, but is

unresponsive. This is beneficial in a number of situations including:

•theft,

• incapacity of the radio user, or

• allowing the initiator of an emergency call to communicate hands-free in an emergency

situation.

In MOTOTRBO systems, Remote Monitor is configured in portable and mobile radio CPS. To allow

a radio to use this function, it must be enabled in the CPS “Menu” settings. To permit (or prevent) a

radio from receiving and responding to this command, go to the “Signaling Systems” settings in the

CPS. When a radio is configured to decode the remote monitor command, the duration that the

target radio transmits after receiving a Remote Monitor command is also set in the CPS “Signaling

Systems” settings of the target radio.

The Remote Monitor feature may be activated on a disabled radio. Remote Monitor could also be

programmed to be activated on radios that are in emergency mode only.

2.3.2.4 Radio Check

The Radio Check feature checks if a radio is active in a system without notifying the user of the

target radio. Besides the Busy LED, there is no other audible or visual indication on the checked

radio. The receiving radio automatically and silently responds with an acknowledgement to the

initiating radio.

This feature is used to discreetly determine if a target radio is available. For example, if a radio

user is non-responsive, Radio Check could be used to determine if the target radio is switched on

and monitoring the channel. If the target radio responds with an acknowledgement, the initiator

could then take additional action such as using the Remote Monitor command to activate the

target radio’s PTT.
