GPS Accuracy
The GPS Location Service accuracy depends on the GPS coverage and the selected accuracy mode.
In good GPS coverage (at least -137 dBm or in open sky), the location accuracy presents as follows:
• In high accuracy mode, the accuracy is:
- 5 m for 50% of location reports.
- 10 m for 95% of location reports.
• In power optimized or normal mode, the accuracy is:
- 20 m for 50% of location reports.
- 50 m for 95% of location reports.
NOTICE:
The presented values depend on variety of factors, for example the view on the sky. To
optimize the GPS performance the radio should have the clearest possible view of the open
sky.
The use of the high capacity battery is recommended, especially when high accuracy mode is
used.

Home Mode Display Text Message
Your radio is provided with a feature that allows your service provider to send special text messages to
the display. The message is limited to 24 characters. The message stays on the home screen until a
new home mode display message is received. Power cycle your radio to replace the Home Display
message to the predefined one.
5.4
Radio Messaging System (RMS)
NOTICE: This feature is a selling feature.
The Radio Messaging System (RMS) feature allows the radio to receive and send RMS messages
through the TETRA network using the Short Data Service (SDS-TL) or Status (STS) as the transport
layer.
NOTICE: One-Touch Buttons are disabled in the RMS mode.
There are two types of RMS messages:
• RMS Status – a predefined code that is sent bidirectionally between the radio and the service
provider. The radio can have up to one hundred statuses that are assigned to numeric keys from 0
to 9. A received RMS status is displayed on the home screen.
• RMS Free Text – (available in SDS-TL only) a unidirectional message containing free text that is
sent to the radio by the service provider. Since this type of message may be longer, the radio
displays only its beginning on the home screen. To view the full message, go to Menu →
Messages → RMS Box.
The latest RMS free text or the latest received or sent RMS status is kept on the home screen until the
next power cycle.
