The Audible Key Tone function allows you to change the Volume and Tone of the audible sounds that are made when you use
the Trim Switches, Rotary Dial, Auxiliary Lever, Push- Button Rotary Dial and the Timer function. The Volume can be Increased
or Decreased (or Muted) and the Tone can be changed to suit your preference.
Changes made using the Audible Key Tone function also affect the audible sounds that are part of the Timer function.
For example, if you Mute the Audible Key Tones, the sounds that are part of the Timer function will also be Muted.
Transmitter warning alarms, such as the Low Voltage Alert alarm, are unaffected.

The Voltage Alarm function allows to specify the voltage at which the transmitter Low Voltage Alert and Low Voltage Limit
alarms will sound. This allows you to choose custom voltage settings to match the type of transmitter battery you're using. For
example,if you're using a 6 cell NiMH battery pack or a 2S LiPo battery pack, you can set the Low Voltage Alert alarm and the
Low Voltage Limit alarm voltage values to suit.
This table shows the different Alert and Limit Voltage values we recommend programming.
Changing the Low Voltage Alert Alarm Value:
The Low Voltage Alert alarm will sound to indicate the transmitter batteries are getting low and should be replaced or
recharged. We suggest stopping use as soon as safely possible and replacing or recharging the transmitter batteries. The Low
Voltage Alert alarm will sound each time the transmitter battery voltage decreases by 0.1 volt. To clear this alarm, press the
BACK/CANCEL key or the Push-Button Rotary Dial.
To ensure the safety of your model and your transmitter battery, we suggest using the Alert and Limit Voltage values
shown in the table above. We don't suggest using values lower than recommended.
