INSTALLATION OF ACCESSORIES

ANTENNA INSTALLATION

The supplied antenna provides good results over the entire frequency range of the transceiver. However, for enhanced reception on certain non-Amateur frequencies, you may wish to connect an antenna designed specifically for that frequency range, as the supplied antenna is necessarily a compromise outside the Amateur band, and cannot be expected to provide high performance at all frequencies.

To install the supplied antenna, hold the bottom end of the antenna, then screw it onto the mating connector on the trans- ceiver until it is snug. Do not over-tighten by use of extreme force.

Notes:

￿Never transmit without having an antenna connected.

￿When installing the supplied antenna, never hold the upper part of the antenna while screwing it onto the mating connector on the transceiver.

￿If using an external antenna for transmission, ensure that the SWR presented to the transceiver is 1.5:1 or lower, to avoid excessive feedline loss.

INSTALLATION OF FNB-83 BATTERY PACK

The FNB-83is a high-performance Ni-MH battery providing high capacity in a compact package. Under normal use, the FNB-83may be used for approximately 300 charge cycles, after which operating time may be expected to decrease. If you have an old battery pack which is displaying capacity which has become diminished, you should replace the pack with a new one.

Installation of the battery is easy and quick:

￿Insert the battery pack into the battery compart-

ment on the back of the radio while tilting the Belt Clip outward, then close the Battery Pack Latch until it locks in place with a “Click.”

￿ To remove the battery, turn the radio off and

remove any protective cases. Open the Battery

Pack Latch on the bot-

tom of the radio, then slide the battery downward and out from the radio while tilting the Belt Clip out of the way.
