Maintenance
- **Cleaning**: Regularly clean the transmitter keypad and pagers. It is recommended to wipe the screen printing position of the keyboard keys with water or 75% alcohol. Do not use kitchen cleaner or vinegar, as these may damage the device.
- **Charging Pins**: If a pager is not charging, ensure the charging pins on both the pager and the base are clean and free from debris. Gently wipe them with a dry cloth or a cotton swab moistened with alcohol.
- **Battery Care**: To prolong battery life, avoid fully discharging the pagers frequently. Charge them regularly, especially after heavy use.
