CHARGING BATTERIES

Before operating your micro truck for the fi rst time, you need to properly charge the receiver battery pack and the starterbox battery pack.

USE THE PROPER BATTERY CHARGER

We strongly recommend using a high-quality peak-detection charger with automatic shut-off. The charger should be specifi cally designed for charging NiMH batteries used
in the receiver pack and starterbox battery pack. Charge each pack at its recommended rate, and do not overcharge or damage or injury may result. Carefully follow the
manufacturer’s instructions that accompany the battery charger.

INITIAL CHARGING & CYCLING THE BATTERY PACKS

The receiver battery pack and starterbox battery pack must be cycled before fi rst-time use. When cycling the receiver battery pack for the fi rst time, carefully follow these instructions:

1. Set the charge current to 120 mA (0.12A) for 1200mAh battery pack or to 140 mA (0.14A) for 1400mAh battery pack.

2. Charge each battery pack for 14-16 hours. During charging it may happen that the charger will stop charging while the battery pack is not fully charged. In such case you
can continue charging until the battery pack is fully charged. This may happen one or more times during charging and this issue is related to the type of charger or type of
charging used.

3. After 14-16 hours disconnect the battery pack, even if the charger is still charging it.

4. Let the battery pack rest for 1 day.

5. After 1 day discharge the battery pack. Set the discharger to a 1.2A discharge rate for 1200mAh battery pack or to 1.4A discharge rate for 1400mAh battery pack, and set the
discharge cut-off voltage to 5.4V for the pack (0.9V per cell).

6. Let the battery pack rest for 6 hours.

Your battery packs have now been cycled and you can use them safely.

RAPID CHARGING

After you have initially charged and run the receiver and starterbox battery packs, you can rapid charge the packs afterwards.

Using a peak-detection charger, set each battery pack to charge at the proper rate (1.0A for receiver pack, X.XA for starterbox battery pack). Do not use higher charge currents;

rapid charging is done at a higher current, so the battery pack may generate too much heat and explode or vent. Never leave the battery pack unattended while it is charging. If
the battery pack becomes too hot (113°F or higher), stop charging immediately.

DISCHARGING AND STORAGE

After use, we DO NOT RECOMMEND discharging the packs completely, as this will damage the packs. You can safely recharge the packs immediately after use without any
performance degradation. If you will be storing the packs for longer than a month, partially discharge the pack down to approximately 40% capacity.

IMPORTANT WARNINGS

A new, unused battery pack is guaranteed against manufacturer‘s defects and workmanship. Any damage due to misuse by the user will be repaired at the user‘s expense.
There is no warranty expressed or implied that covers damage caused by normal use, or covers or implies how long the battery pack will run (run time), or last before requiring
replacement due to normal use and normal cell degradation. XRAY shall not be liable for any damage caused by overcharging, battery failure, improper charging or discharging,

use of non-approved chargers, use of non-approved batteries, and alternations or modifi cations of any kind to the charger, batteries, switches, or wiring.

WARRANTY

INSTALLING THE ANTENNA

You must install the antenna tube before operating your micro truck.

• Never disassemble the battery pack or peel away the cover.

• Keep the battery pack away from water.

• Do not touch the battery pack with wet hands or wet objects.

• Do not subject the battery pack to strong impacts and short circuits.

• Keep the battery pack away from fi re and fl ammable objects.

• Disconnect the battery pack when it is not in use.

• Do not put metal objects in the battery pack connector or touch the terminals

• in the connector.

• Do not throw away the battery pack when you no longer need it. Bring it to the shop from which you bought it, or to a shop offering battery recycling service.

• If leaked battery alkaline electrolyte gets in your eyes or on your skin, fl ush thoroughly with clean water and consult with a doctor immediately.

• Regularly check the wiring for damage. While running the truck, vibration or movement may cause damage to the wires which if left unchecked may result in a short circuit. If

any wire insulations becomes damaged, please dispose of the battery pack properly and do not use it, nor try to repair it.

• You are responsible for the proper use of this battery pack and any damage that may occur due to its use or misuse. XRAY is not liable for any injury, damage, or harm caused

to any person or property arising from the use or misuse of their products.

1. Locate the black antenna wire that exits the receiver. The receiver

is mounted on the top of the servo.

2. Pull the wire straight with your fi ngers and then insert the end of

the wire into one end of the antenna tube. Push the wire all the way
through the antenna tube.

3. Pull the remaining wire through the antenna tube, and then insert

the base of the antenna tube into the molded post on the chassis
to which the servo is mounted.

4. Fold the remaining antenna wire over the top of the tube. The

remaining wire can stick up.

TIP:

Spray a small amount of window cleaner on the antenna wire to
make it easier to push through the antenna tube.
Do not push the transmitter antenna down from the top. Pull it down
from the bottom, one segment at a time, to prevent binding and
kinking the antenna mast.

CAUTION !!!

Do not shorten the length of the antenna wire. Its length is tuned to the frequency band; cutting it may severely shorten the radio system’s range.
