5. Product Service Information ( for USA & Canada only )

In the event you would require service to your radios, please send the parts to ::

Hitec RCD USA, Inc. Service Department
12115 Paine St.
Poway, CA 92064

Please include your name address and telephone number along
with a brief description of the failure or the work that you are requesting to be done.

6. Precautions

- Always turn your transmitter on first and off last.

- Never operate your system without first performing a proper range check.

- FCC regulation in the USA prohibits changing the crystal in your transmitter.
For channel changes send your system to an authorized service/repair center.

- Never fly around or over houses, people or power lines.

- Always charge your batteries before you fly.

- It's a good idea to check your receiver batteries with a tester like the Hitec
Power Mate II (part# 44110). This will verify the charge level in your receiver batteries.

- Always fly responsibly and respect the rights of others.

- Make sure your frequency is clear before turning on your system.

Congratulations again and have fun!

H. Stick Lever Tension Adjustment

- The unique open-stick assembly provides fully adjustable stick tension to adjust
the "feel" of the sticks in your hands.

- You may adjust the stick tension of your sticks to provide the "feel" that you like
for flying. To adjust your springs, you'll have to remove the rear case of the
transmitter. Using a screwdriver, remove the six screws that hold the
transmitter's rear cover into position, and put them in a safe place. Gently ease
off the transmitter's rear cover and move it to the right side of the transmitter,
carefully turning it as you would turn the page of a book. Now you'll see the view
shown in the illustration. Using a small Philips screwdriver, rotate the adjusting
screw for each stick for the desired spring tension. The tension increases when
the adjusting screw is turned clockwise, and decreases for counterclockwise
motion. When you are satisfied with the spring tensions, you may close the transmitter.
Very carefully reinstall the rear cover. When the cover is properly in place, tighten the six screws.

Laser 4 Stick Lever Tension

I. Trim Levers

-

The trim levers associated with each control stick

the tracking of the aircraft.

- (Caution) Make sure the trims will move the surface past neutral when moved to
their extremes. This will assure you have adequate trim control.

- After your plane's first test flight, note the positions of the control surfaces that
required trim. Next, center the trims and turn the receiver off. Now adjust the
control linkage on the plane so the surfaces are in the same position before the
trim levers were re-centered.

- Turn on the radio and receiver and recheck the control surfaces to ensure that all
the corrections were applied in the proper direction.

J. Dual Rates (Available on Laser 6 only )

- The Laser 6 offers the user a choice of 2 rates on CH 1, aileron and CH 2, elevator.
Dual rates are used to lessen and increase the servo "throw" or movement of the
control surface while in flight. For example, a plane traveling very fast will require
small servo or stick movements and should be flown on "low rates". While the
same plane, flown slower might require more servo throw and could be flown on higher rates.

- Adjusting the Dual Rates

- With the dual rate switch in the low position, you will have full, or 100% throw.
When adjusting for a lower rate, move the Aileron dual rate switch up to the
higher position. Fully deflect the control surface with the transmitter stick to the
left or right and hold it there. Then adjust the "pot" located on the lower left
corner of the transmitter case with the provided screwdriver. You will see
the control surface move when you turn the pot, adjust it accordingly. Repeat this
process to adjust the Elevator dual rate setting.

K. Landing Gear Switch ( Available on Laser 6 only )

- The landing gear switch will operate a servo in the CH 5 slot of the receiver. This
is typically used for air or mechanically operated landing gear, which is not proportional.

L. End Point Adjustment (E.P.A) ( Available on Laser 6 only )

- CH 3. (Throttle)

- This function allows for individual adjustment of the high and low throttle servo
end points. Adjust the pots on the face of the radio with the provided screwdriver to
position the throttle servo so it does not bind or "buzz" when at high or low stick.

2. Battery Management

A. Transmitter/Receiver battery charging

- The initial charge on your system should be at least 24 hours to ensure a full charge.

- Subsequent charges should be at least 12 - 20 hour.

- It is best to put your system (TX and RX) on charge the night before you plan to use it.

- To charge your batteries, first make sure your transmitter and receiver are off;
then connect the wall charger outputs to the charging jack on the transmitter and
the charge receptacle on the switch harness or directly to the battery.
Make sure the green (TX) and red (RX) lights come on. If it does not,
check for proper connection and/or power to the outlet.

- Be careful not to leave your transmitter or receiver battery on charge for
more than 24 hours to prevent any damage to the battery or charger.

- Always charge your system before you go out to fly.

B. Battery Spacer

- Pull out the tab of the provided battery spacer first whenever
you are taking the battery packs out.

- The size of nicad packs (part# 58207) are smaller than dry battery packs (part# 58101) so

plug in the battery spacer into the correct slots so that the battery pack is held tight in its place.

3. Operation

A. Trainer system

- The Laser 4/6 is equipped with a trainer system that allows for master, student control

- Use trainer cord, part# 58310

- When setting up the trainer system, make sure the student radio is set up properly
so the trims and servo reversing are the same as the master.

- To activate the trainer system and transfer control to the student pull and
hold the trainer switch located on the top let of the transmitter.
Releasing the switch will restore immediate control back to the master.

B. Range checking

- Always perform a range check before each operation.

- Perform range check by walking away from the aircraft with the transmitter antenna collapsed.

- You should have complete control from a distance of 60 - 90ft ( 20 - 30m ).

- If the controls are erratic before the minimum distance is reached,
do not fly until the problem is resolved.
