WARNING! Repair or alteration of the device beyond the scope of the maintenance instructions in this manual or by anyone other than General Monitors or General Monitors-approved service personnel can cause incorrect operation of the device and put persons who use this device for their safety at risk of serious injury or death.

The device has components that can be damaged by electrostatic discharge (ESD). When you do work with the device wiring, be careful to touch only the connection points. The warranty does not supply coverage for components that are damaged by ESD.

Use ONLY a damp cloth to clean the device. Otherwise, electrical shock or ignition from ESD can occur.

Use ONLY Industrial Strength Windex® with Ammonia D (General Monitors PN 10272-1) to clean the optical window. The optical window material is sapphire, not glass. Using any other commercial glass cleaner will cause damage to the optical window. The warranty does not supply coverage for optical windows that are damaged in this way.

Clean the optical window every 30 days at a minimum. Do sensitivity checks regularly.

Remove debris and film buildup on the optical window and reflectors regularly to make sure that the device has the correct sensitivity and to prevent COPM Faults.

Use a clean, soft, lint-free cloth, tissue, or cotton swab soaked with Industrial Strength Windex with Ammonia D to clean the optical window and UV/IR reflectors.

Use a clean, dry, cloth to rub the optical window until it is clean. Do NOT touch the lens with your fingers.

Let the optical window and UV/IR reflectors air-dry fully.
