Safety & Warnings
The manual provides the following safety warnings and precautions:
1. Do not transmit with high output power for extended periods to prevent overheating.
2. When using an external power supply, connect the recommended DC cable to the DC IN jack on the transceiver.
3. When connecting the transceiver to a cigarette lighter socket in a mobile, use the recommended cigarette lighter cable.
4. Before recharging a mobile battery, unplug the cigarette lighter cable from the lighter socket to avoid voltage spikes that can damage the transceiver.
5. Do not recharge the NiCd battery pack for more than 15 hours (PB-33: 30 hours) with an external power supply.
6. Do not expose the transceiver to long periods of direct sunlight or place it close to heating appliances.
7. Do not place the transceiver in excessively dusty or humid areas, or on unstable surfaces.
8. If an abnormal odor or smoke is detected from the transceiver, turn off the power immediately and contact a KENWOOD service station or dealer.
9. Do not modify the transceiver unless instructed by the manual or approved by KENWOOD.
10. The recommended transceiver duty cycle is 1 minute of transmission and 3 minutes of reception. Longer transmissions or extended operation in High power mode may cause the back of the transceiver to get hot. Avoid placing it where the heat sink might contact plastic or vinyl surfaces.
11. Nickel-Cadmium batteries must be recycled or disposed of properly, and state laws may vary regarding their handling and disposal. Contact an Authorized KENWOOD Dealer for more information.
