4.1 การชาร์จแบตเตอรี่

Before first use, fully charge the supplied lithium-ion battery pack. Connect the AC adapter to the drop-in charger, then place the radio with the battery pack into the charger. The charging indicator will illuminate. A full charge typically takes several hours and provides up to 15 hours of talk time.

4.2 การติดเสาอากาศ

Carefully screw the antenna onto the connector at the top of the radio until it is finger-tight. Do not overtighten, as this can damage the connector.

4.3 การติดคลิปหนีบเข็มขัด

Attach the swivel belt clip to the designated slot on the back of the radio or battery pack. Ensure it clicks securely into place to prevent accidental detachment during use. Periodically check the security of the clip.

5. คู่มือการใช้งาน

5.1 การเปิด/ปิดเครื่องและการควบคุมระดับเสียง

To power on the radio, rotate the top-mounted knob clockwise. Continue rotating to adjust the audio volume. To power off, rotate the knob counter-clockwise until it clicks.

5.2 การเลือกช่องสัญญาณ

ใช้ Up และ ลง arrow buttons to change channels. The IC-M88 supports various channel groups:

• US Channels: For use in United States waters.
• ช่องรายการต่างประเทศ: For use in international waters.
• Canadian Channels: For use in Canadian waters.
• Land Mobile Channels: 22 free channels (146 to 174 MHz) for commercial use (requires FCC license).

กดปุ่ม U/I/C/L button to cycle through these channel groups.

5.3 Transmit Power Level

กดปุ่ม H / L button to toggle between High (5W) and Low (1W) transmit power. Use low power for short-range communication to conserve battery life and reduce interference. High power is for maximum range.

5.4 ฟังก์ชันการสแกน

The IC-M88 offers multiple scanning functions to monitor channels:

• Tag สแกน: Scans channels that have been marked as 'tag' channels. Use the TAG button to mark or unmark channels for scanning.
• การสแกนลำดับความสำคัญ: Monitors selected tag channels while also continuously checking Channel 16 for distress calls.
• สแกนอัตโนมัติ: Automatically initiates scanning when no signal is detected on the current channel.

กดปุ่ม เอสซีเอ็น button to initiate or stop scanning.

5.5 Dual Watch and Tri-Watch

ฟังก์ชันเหล่านี้ช่วยให้คุณสามารถตรวจสอบหลายช่องสัญญาณพร้อมกันได้:

• นาฬิกาคู่: Monitors a selected working channel and Channel 16.
• ไตร-วอทช์: Monitors two selected working channels and Channel 16.

กดปุ่ม คู่ button to activate these modes. These functions are crucial for ensuring you do not miss important emergency calls while engaged in other communications.

5.6 Weather Channels and Alerts

กดปุ่ม CH/WX button to access NOAA weather channels. The radio can also provide weather alerts, automatically switching to the appropriate weather channel when a storm warning or other alert is broadcast.

5.10 ฟังก์ชันตรวจสอบตัวเอง

The IC-M88 features a self-check function that monitors internal temperature, connected battery voltage, and water intrusion. Consult the comprehensive user manual for detailed instructions on accessing and interpreting the results of the self-check function.

6. การบำรุงรักษา

6.1 การทำความสะอาด

ควรทำความสะอาดวิทยุเป็นประจำด้วยผ้าเนื้อนุ่มและแห้งamp cloth. Ensure all caps and covers, especially for external ports, are securely closed to maintain its waterproof integrity. Do not use harsh chemicals, abrasive cleaners, or solvents, as these can damage the radio's finish and seals.

6.2 การดูแลแบตเตอรี่

To maximize the lifespan of your lithium-ion battery, avoid fully discharging it frequently. Recharge the battery before it is completely depleted. When storing the radio for extended periods, ensure the battery is partially charged (around 50%) and store it in a cool, dry place away from direct sunlight.

7 การแก้ไขปัญหา

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

• วิทยุไม่เปิด: 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.
• Water intrusion warning: If the self-check function indicates water intrusion, immediately power off the radio and consult a qualified service technician.
