Universal Time Display
The radio can present time information to the user. The time is derived from an internal clock. The
radio maintains the clock both when the radio is powered on and powered off.
NOTICE: If the power is lost, for example due to the flat battery, the internal clock is not
maintained.
To ensure the time displayed is accurate, the time is displayed only if within the last 48 hours either of
the following events have occurred:
• The radio has received a network time update from the system.
• You have manually updated the time.
Also, as the internal clock is not maintained after a power loss event, the time is not displayed until
either these events occur.
The feature is enabled or disabled and the default configuration can be set for the radio using the
Customer Programming Software (CPS) or radio MMI.
The radio display supports the following:
• Twenty-four-hour and twelve-hour formats.
• DD/MM/YY, MM/DD/YY, DD-MON-YY, and YY/MM/DD date formats.
You can change the time, date, and offset information through the MMI, depending on the codeplug
settings. Depending on configuration, system broadcast information can have higher priority than data
entered manually. Thus time, date, and offset information entered from the MMI is overwritten, when
data is received from the SwMI. The radio provides user indications upon crossing to another time
zone, when a new Mobile Country Code (MCC) broadcast received.

DMO Gateway and Repeater Communication
The radio provides the capability of communicating in Direct Mode Operation (DMO) with a Trunked
Mode Operation (TMO) group via the Interoperability (IOP) certified gateways.
A DMO repeater re-transmits information received from one DMO radio to other DMO radios over the
DMO air interface.
For each DMO talkgroup, the radio allows operating in one of the following modes:
Radio to radio only
The radio initiates calls only on a talkgroup directly and not through a gateway or repeater.
Auto gateway
The radio can initiate calls on the selected talkgroup directly with another radio or through any
available gateway that is detected as present.
Repeater
The talkgroup links to a DMO repeater.
Specific gateway and repeater
The radio uses only the gateway with the specified gateway address for the talkgroup and/or a
DMO repeater.
Automatic gateway and repeater
The radio uses the first available gateway for a talkgroup and/or a DMO repeater. If either specific
gateway or auto gateway mode is chosen, and a suitable gateway is found, all outgoing calls are
placed through the gateway. If a suitable gateway is not found, or a call setup through the gateway
fails, the radio attempts to set up the call directly.
When operating on a gateway and/or repeater, the radio indicates the communication mode.
