7. Penyelesaian masalah

This section addresses common issues you might encounter with your IC-M88 radio.

• Radio tidak dihidupkan: Ensure the battery pack is fully charged and correctly installed. Verify that the power/volume knob is rotated clockwise past the 'off' position.
• Missing calls or poor reception: Check that you are on the correct channel and within range of the transmitting station. Ensure the antenna is securely attached. If the battery save function is enabled, consider disabling it as it may occasionally affect reception sensitivity.
• Poor transmission range: Confirm the transmit power is set to High (5W) using the H/L button. Ensure the antenna is properly connected and undamaged. Obstructions or environmental factors can significantly affect range.
• Battery detaching from belt clip: Ensure the belt clip is securely latched to the radio or battery pack. If repeated detachment occurs, some users have found success by applying a small amount of silicone rubber to the battery latch switch to increase friction, ensuring it can still be removed for battery replacement or service.
