6.2. Maintenance

General Cleaning Recommendation

Under recommended operation of the SL-RAT device, maintenance should be minimal. It is recommended to clean the exterior of the SL-RAT device with a mild disinfecting wipe or a mild general purpose cleaner after each daily use. Do not use harsh chemicals on the exterior. Do not open the control box. Do not remove the TX speaker and/or the RX microphone in order to perform maintenance (cleaning or otherwise).

TX Speaker and RX Microphone

User maintenance is required if the TX speaker or RX microphone are fouled with debris, dirt, or have been exposed to harsh chemicals (airborne or otherwise). Under any of these conditions, they are required to be cleaned.

Cleaning – DO NOT USE CLEANERS OR CHEMICALS. Use a mild liquid dish soap and water mixture on a clean rag to clean the exterior of the TX speaker or RX microphone.
If the SL-RAT™ device is regularly exposed to harsh environments, then the SL-RAT™ TX and RX should be returned to the factory at least one time per year to provide more extensive cleaning as well as an inspection of seals, cables, and electronics.

Opening the control box will void the warranty. All repairs requiring opening the control box should only be performed by factory-trained technicians.

Lock Knob Maintenance

The two lock knobs (Figures 1 and 2) on both the SL-RAT™ RX and TX should be oiled at least once per year, or more often if the device is regularly exposed to wet weather, wet environments, and/or harsh environments.

Battery

The customer has the option of sending the equipment in to the manufacturer for replacement or ordering a replacement battery and installing it themselves.

The rechargeable Li-ion batteries can only be replaced with a battery purchased direct from the manufacturer. All other batteries are prohibited. Installation and use of any other battery will void the warranty and may cause equipment failure or a safety hazard.

Proper battery installation instructions will be provided by the manufacturer to the end-user upon purchase of a new battery.
