Getting Started
Antenna
Your radio must be fitted with an antenna at all times (unless your radio is used with an external
antenna such as an RSM) during operational periods. Transmitting without an antenna attached
may damage the product. Your radio is designed for use with Sepura approved antennas.
Always ensure that the seal between the antenna and the radio is maintained.
Never touch the antenna when the radio is transmitting. Ensure your radio is powered off before
fitting or removing the antenna.
Fitting the antenna
1. Insert the base of the antenna into your radio's antenna connector.
2. Rotate the antenna clockwise until it is finger tight. Then apply another 1/4 turn clockwise.
Removing the antenna
Rotate the antenna counter-clockwise until it can be removed from the radio.
