Maintenance
Visual inspection
Inspect for damage
The following steps check for obvious damage.
„ General
‹
Inspect the equipment (transmitter, receiver, etc.) case for cracks or other
physical damage. Do not use a transmitter that is damaged. Refer all
damaged equipment to qualified personnel.
‹ Inspect all external connections for loose connectors or frayed cables. Have
any damaged connectors or cables replaced by qualified service personnel.
„
Transmitter
‹ Inspect the transmitter case for damage that may affect the environmental
seals (such as if the unit was dropped and the case seals opened as a result of
the impact). Do not use a transmitter that has seals that have been
compromised.
‹
Inspect the membrane switch for the Graph and Verify Leads controls. If
the membrane is cracked or damaged, do not use the transmitter.
‹ Inspect the leadwire connections for corroded or bent connector pins. Do not
use a transmitter with bad leadwire connectors.
‹
Inspect the leadwires for cracks or other damage. Replace leadwires that are
cracked, damaged, or no longer flexible.
‹ Open battery compartment and inspect the battery contacts. Clean them if
they are dirty or corroded.
‹
The battery compartment is not sealed and may be exposed to moisture. If
there are any visible signs of moisture within the battery, return for service.
‹ Inspect the dust covers before each use to verify that they are securely
attached.
If a transmitter or leadwires fail any of the above inspections, immediately service or
replace it.
