This device is fitted with a Male SMA connector. To mount the antenna (Female SMA Connector), align the
two connectors and turn the antenna clockwise until it stops.
When installing the antenna, install it by holding the base and turning.
If an external antenna is used, ensure that the ‘SWR’ is about 1.5:1 or less to avoid damage to the
device’s transistors.
Holding the antenna with your hand or wrapping the outside may cause subpar operation of the
device.
Never transmit from the device without an antenna.
Belt Clip
On the back of the device, above the battery, there are two parallel screws. Remove these and
align them so that they go through the holes on the belt clip as they are screwed back into the
device body to securely affix the belt clip.
Install the belt clip at the rear of the battery compartment cover as shown in the figure to the
right.
Do not use glue to affix the screws onto the battery clip. Application of glue may cause
