Transmitter Non-RF Application Problems
10
1. The battery could be inserted improperly. Check
that the terminals of the battery are oriented
correctly with the battery contacts.
2. Open the battery door and check the battery
contacts. If they are corroded, clean them. If they
appear damaged, replace the battery contacts.
Also, check the screws that connect the battery
contacts to the Case Assembly.
3. Zinc-air batteries cannot be used in transmitters
with SpO
2
hardware because zinc-air batteries
cannot reliably supply enough current at start-up of
the transmitter to make sure the transmitter
functions properly. Even if SpO
2
is not being
monitored, if the transmitter has the SpO
2
hardware installed, a zinc-air battery cannot be
used. A lithium or alkaline battery must be used.
4. Remove the battery and separate the case assembly
from the transmitter’s internal electronics. Using an
ohmmeter, check the resistance from the battery
contact inside the case to its corresponding
external battery contact. The resistance should be
less than 1 ohm. If it is not, replace the battery
contacts.
5. SpO
2
might be affecting the battery. Replace the
SpO
2
PCB.
