8.5.5.3 GPS Report
The GPS Report feature allows the radio to report its location information to the control center or trunking system.
In conventional mode, you can report the GPS data to the control center by pressing the preprogrammed GPS
Report key. Alternatively, you can consult your dealer to configure the GPS trigger, allowing the radio to
automatically report the GPS data upon power-on/off, or according to the preset time or distance interval.
In trunking mode, with the GPS Active Report feature enabled by your dealer, the radio automatically reports
the GPS data when reaching the preset time or distance. If the radio is enabled with the GPS Report in Voice
feature, the radio actively reports GPS data during a call.
8.5.5.4 Quick GPS
Based on GPS standard time, the Quick GPS feature divides the GPS upload time into several equal-length time
slices. These time slices are allocated to radios with different configurations for periodic upload and single
upload. Each radio uses the same GPS upload time length to upload GPS data, improving upload efficiency and
reliability.
If your dealer configures the feature to a digital channel, the channel only reports the quick GPS data.
8.6 BT
BT is a wireless technology that supports short-distance communications and data exchange between devices. You
can connect the radio to a BT device through the built-in BT module.
To derive optimal communication quality, it is recommended to use the BT devices approved by the
Company.
If BT earpieces of other companies are used, you must use them with the wireless ring PTT of the
Company. Otherwise, the earpieces cannot transmit
To enable or disable the BT feature, do either of the following:
