Safety & Warnings
This equipment generates or uses radio frequency energy. Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual. The user could lose the authority to operate this equipment if an unauthorized change or modification is made.
Nickel-Cadmium batteries must be recycled or disposed of properly. State laws may vary regarding the handling and disposal of Nickel-Cadmium batteries. Please contact your Authorized KENWOOD Dealer for more information.
Before recharging a mobile battery, unplug the cigarette lighter cable from the lighter socket. Voltage spikes sometimes present during charging can damage the dual bander.
Do not recharge the NiCd battery pack for more than 15 hours (PB-33: 30 hours) with an external power supply. Switching ON the power supply begins recharging the battery pack automatically.
Do not expose the dual bander to long periods of direct sunlight or place the dual bander close to heating appliances.
Do not place the dual bander in excessively dusty or humid areas, or on unstable surfaces.
If an abnormal odor or smoke is detected coming from the dual bander, turn OFF the power immediately. When using a regulated power supply, also remove the DC cable from the dual bander. Contact a KENWOOD service station or your dealer.
Do not modify this dual bander unless instructed by this manual or by some other approved KENWOOD communication.
The recommended duty cycle is 1 minute of transmission and 3 minutes of reception. Longer transmissions or extended operation in the High power mode may cause the back of the dual bander to get hot. Do not place the dual bander where the heat sink (rear panel) might come in contact with plastic or vinyl surfaces.
Transmitting with the supplied antenna near other electronic equipment can interfere with that equipment. Also, transmitting near a regulated power supply that is not recommended by KENWOOD may cause the power supply to output an extremely high voltage. This voltage could damage both your transceiver and any other equipment connected to the supply.
