RF power setting
IMPORTANT: Lower output power will reduce the RF transmission
distance and higher output power will extend the possible RF transmission
distance. However, higher output power places slightly more load on the
battery and will reduce operating duration faster than lower output power.
1Press-release MENU button until the CHANNEL-RF POWER
page appears.
2Press and hold SET button until the RF power figure flashes to
denote readiness for setting.
3Press-release SET (UP) or MENU (DOWN) button to choose an
