- ID code is transmitted for about 0.3 seconds after pushing the transmitter button. Therefore pushing the button again within about 0.3 seconds after pushing it is not applicable. Always push the button every a second.
- Since the battery voltage does not drop fully if the button is pushed only four times or less, it can not be properly examined to see whether is good or bad. Always push the button five times.
