3.2 Arming and Disarming the System
To arm or disarm the security system, enter your valid user code followed by the appropriate arming command (e.g., "AWAY," "STAY"). Consult your system's user manual for specific arming/disarming sequences.
3.3 Function Keys

4. Maintenance
Regular maintenance ensures the longevity and proper functioning of your NX-148E keypad.
4.1 Cleaning
Clean the keypad's exterior and LCD screen periodically with a soft, dry, lint-free cloth. For stubborn marks, slightly dampen the cloth with water. Do not use abrasive cleaners, solvents, or spray liquids directly onto the keypad.
4.2 System Checks
Periodically test your entire security system, including the keypad, according to the recommendations in your main alarm control panel manual. This typically involves testing arming/disarming, zone faults, and alarm activations.
