Trim Operation and Maximum Travel.

Changing the trim can effect the overall settings, when adjustments are
made with the trims, please recheck your installation for maximum servo
travel.

When Trim movement goes to extremes

That means if you make a lot of trim movement to get a servo to the
neutral position, please reposition the servo horn or servo saver on the
servo and inspect your linkage installation.

Caution:

When find
the direction
is wrong,
change to
relevant REV
button.

1. When adjusting
the TRIM button,
the "ST.DR" LED
flashes in GREEN.

Racer Tip

When using a electronic speed control, please set the throttle trim to
neutral and make adjustments to the speed control. On a gas powered
model, set the trim to neutral and adjust the linkage to the point where
carburetor is fully closed in accordance with the engine instruction
manual.

Trim Operation and Travel

Trim adjustments will effect the overall servo travel, so please check the
(backward) movement after the adjustment.

Battery Replacement

1) Slice the battery cover out of the transmitter in the direction of the

arrow. 2) Remove drained batteries. 3) Load the new AA size
batteries. Pay very close attention to the polarity marking and reinsert
accordingly. 4) Slide the battery cover back into the case.

Caution

Always ensure reinserted batteries are in the correct polarity order. If
batteries loaded incorrectly may cause damage to the transmitter.
When the transmitter is not in use, always remember to remove the
batteries. If the batteries do happen to leak, clean the batteries case
and contacts thoroughly. Make sure the contacts are free of corrosion.

Battery Disposal

1. Hold the RF-TEST button until the "ST.DR" light turns to RED.
Meanwhile the output power of transmitter reduce to lower mode
18dbm, which then reduces power consumption.

2. When pressing the RF-TEST button again, the "ST.DR" light
deactivate, and output power becomes normal 20dbm which
subsequently can control more range.

Function

Using this function to adjust servo travel.
The default is 100%. When pressing D/R, the front
light flashes, and the value quickly switch to 70%.

Function

All the setting in the system will be reset to the
