Maintenance

Storage

Use the following guidelines when storing acquisition modules:
• Always remove the batteries when the device is not in use, even for short periods
of time.
• Store in a dry, well-ventilated area.
• Hang the device, using a holder if available.
• If leadwires are attached, they should hang straight.
• Do not coil leadwires or cables around the device.

Battery Compartment Cleaning

NOTE:
This procedure applies only for frequency hopping telemetry transceivers. It
should not be used for other devices.
Under normal operation, the battery compartment should not require cleaning. If the
battery compartment should require cleaning, use the following instructions.
CAUTION:
DEVICE MALFUNCTION — Cleaning the battery compartment in a manner other
than that described in the following procedure may cause the unit to malfunction
and void the warranty.
The battery compartment is not waterproof. Make certain fluids do not enter the
electronics through the air holes in the battery compartment floor.
1. Remove the battery from the battery compartment.
2. Clean the device with a gauze pad or cloth lightly moistened with one of the
following agents:
• Water
• Soap
3. Use a cloth lightly moistened with distilled water to rinse away the cleaning
solution. Make certain that moisture does not enter the electronics area below
the battery compartment floor.
4. Dry thoroughly with a lint-free cloth and allow the battery compartment to air
dry completely prior to closing the compartment door.

Built-In Diagnostic Tests

The host equipment generally contains built-in diagnostic tests to verify the operation
of the electrocardiograph.
These built-in diagnostic tests verify the operation of the acquisition module, as well.
For example, there is a test that records raw ECG data on the thermal paper. This test
checks for noise and gain in the acquisition module. Another test is a serial link test
that determines if the microprocessor in the host equipment is communicating with
the acquisition module.
For details on using these tests, see the field service manual for the host equipment.
