INSTALLING BATTERIES (RADIO)
Note: When the inserted batteries are fully charged, the battery indicator on the
LCD shows full power “ ”. If the battery indicator shows low power “ ” and is blinking, the battery is about to run out. “ ” indicates that the operating voltage is insufficient, the radio will turn off automatically and is unable to turn on. See section 26 for information about how to charge the batteries.

1. Open the battery compartment located at the back of the unit.
2. Correctly install two 18650 lithium batteries by following the polarity diagram.
3. Close the battery door.
Note:
This device has battery detection circuits, supplied with detection buttons located at both ends of the battery compartment. After inserting a lithium battery, press the detection button. When the LED light is on, this indicates that the lithium battery is suitable for use. If the light is off, the battery is damaged and should be promptly replaced.

MW TUNING STEP & FM FREQUENCY RANGE SETTING
MW tuning step (9kHz / 10kHz)
In radio OFF mode, press and hold the [9/10kHz] button on either the radio or remote control . The LCD briefly displays “9 kHz” or “10 kHz” to indicate the selected tuning step.
9 kHz tuning step: MW frequency coverage is 522 kHz ~ 1620 kHz. 10 kHz tuning step: MW frequency coverage is 520 kHz ~ 1710 kHz.

FM frequency coverage settings
In radio OFF mode, press and hold the [FM SET] button on either the radio or remote control , then press repeatedly to select your desired starting point of the FM frequency range (64, 76, 87 or 88 MHz) and wait until the LCD displays “108 MHz” to automatically confirm the setting. LCD displays “ ”, the frequency coverage is 64 ~ 108 MHz. LCD displays “ ”, the frequency coverage is 76 ~ 108 MHz. LCD displays “ ”, the frequency coverage is 87 ~ 108 MHz.

ANTENNA SELECTION AND CONNECTION
Safety Alert
1. When you build an outdoor antenna, you must pay attention to personal safety!
2. An outdoor antenna must be kept away from power lines! It must be windproof, waterproof, and requires protection from lightning strikes.
3. During a thunderstorm, do not use an outdoor antenna! Disconnect the outdoor antenna from the radio.
4. Do not use a gas pipeline or AC power outlet for grounding purposes.
1. Long Wave and Medium Wave antenna:
The S-8800 radio uses a built-in magnetic rod (ferrite) antenna to receive long wave and medium wave signals. Since this ferrite antenna is directional, minimizing interference and achieving the best reception for long wave and medium wave signals requires repositioning of the radio. If necessary, you can connect an external antenna to the “AM ANT.” external antenna socket and a ground wire to the ground (GND.) socket to improve reception. Push the switch to “EXT ANT.” position.
