Transmitter Battery Inspection
- Allow battery to warm to room temperature of 68-86°F (20-30°C). Using a digital circuit tester, measure voltage of each battery while pressing transmitter button. See Fig 1
. If voltage is 2.7 volts or more, reinstall batteries and go to next step. If voltage is less than 2.7 volts, replace batteries.
- Verify system operation with second transmitter. If system operates using second transmitter, replace defective (first) transmitter. If system does not operate and second transmitter is not faulty, check antenna feed and keyless unit.
