Caution

The battery pack isn't fully charged when shipped. It must be charged before use. Charging should be conducted in a temperature range of 0C to +40C (+32F to +104F). Don't modify, dismantle, incinerate or immerse the battery pack in the water as this can be dangerous. Never short-circuit the battery pack terminals, as this can cause damage to the equipment or lead to heating of the battery which may cause burns. Unnecessary prolonged charging (overcharging) can deteriorate battery performance. The battery pack should be stored in a dry place where temperature is in -10C to +45C (-14F to +113F) range. Temperatures outside this range can cause the battery liquid to leak. Exposure to prolonged high humidity can cause corrosion of metal components. Battery-packs are a consuming part. When its operating time becomes considerably short after a normal charge, please consider that the pack is exhausted and replace it with a new one. The battery pack is recyclable. Check with your local waste officials for details on recycling options or proper disposal in your area. Risk of explosion, generation of heat or leak of chemicals inside if the battery is replaced by an incorrect type. Use always the recommended types of batteries in this manual only Use specified genuine chargers only to charge battery packs. Use of other chargers may cause damage to products, you and your property.
2.1.5 Prevent Short Circuiting the Battery Pack

Be extra cautious when carrying the rechargeable battery pack; short circuiting will produce surge current possibly resulting in fire.
DON'T carry with metals of any type, e.g. chains. DON'T carry the battery pack inside bags made of conductive materials. DON'T place in the proximity of metals or conductives, e.g. nails, chains.
Do enclose inside a non-conductive enclosure. (bags or handkerchief made only of non-conductive material)
Do protect by spreading a non-conductive sheet on a flat surface.

2.1.6 Battery-Level Icon

During the operation, a black battery icon indicates that the battery-level is in usable range. When it turns to empty, please charge the pack or replace the cells with new ones.

The selectable offset frequency of this unit is from 0 to 99.995MHz. 1. Press the FUNC key, and while is displayed, press the key to display the current offset frequency and shift direction settings.

2. Each time the key is pressed the shift direction changes as indicated below. A (-) means that the TX frequency is lower than the RX frequency. A (+) means vice versa.

-0.600 +0.600 OST-OF

3. Rotate the dial while the shift frequency is being displayed. Clockwise: each click increases the frequency by one tuning step. Counter-clockwise: each click decreases the frequency by one tuning step. Press the FUNC key and rotate the dial to increase or decrease the frequency in 1MHz steps. 4. Press any key except for the MONI or FUNC key to complete setting.
NOTE: Please refer to "Selective Calling" (page 35) to set the CTCSS/DCS tones usually required for conventional Repeater-Accesses. If the offset frequency is set to exceed the transmitting frequency range of this unit, "OFF" appears on the display and a beep sounds when the PTT key is pressed. You can not transmit in this state.

5.Useful Functions

5. Useful Functions

5.1 Scan Modes

The scan function automatically searches the receiving signals. There are 2 modes for scan-resume condition. Busy Scan: The scan stops when a signal is detected, stays until the signal is gone then resumes scanning. Timer Scan: The scan stops when a signal is detected, and resumes scanning after 5 seconds regardless of receiving status. During scanning, the 1MHz decimal point ( ) on the frequency display flashes. Press any key other than the MONI key to stop scanning. Scanning starts in the direction of the last dial operation (up or down).
