3.0 System Component Installation
3.1 Transmitter Battery
CAUTION
THE BATTERIES MUST BE INITIALLY CHARGED
BEFORE USE. Batteries must be charged for a full twelve
(12) hours before they can be installed in the transmitter.
Using a battery before initially charging will shorten its life
span and can possibly result in an immediate degradation
of service.
Note: You must fully charge the batteries before installing and using in the
transmitter. It takes twelve (12)hours to initially charge or recharge an
exhausted battery. Once a battery is charged, do NOT charge it again until the
transmitter indicates a low charge. You will shorten the battery life by charging
it before it is exhausted. To guard against disruption of service, be sure to
have one battery fully charged or in the process of being fully charged while
the other is in use at all times.
Upon initial start-up, place a fully charged battery in the transmitter. Continue to use it
until the transmitter LED slowly flashes red. The flashing LED indicates you have
approximately five (5) minutes of operation until the transmitter automatically shuts
down (see Topic 0 Use the following instructions to properly operate the equipment:
1. Attach the harness to the transmitter to prevent the equipment from
falling.
2. Make sure of the transmitter you are going to use. Verify that the machine
you want to operate matches the transmitter identification label—the label
allows the operator to identify the machine before starting the equipment.
3. Install a fully charged battery into the transmitter.
4. Make sure all command controls are in the neutral position. All the
command controls associated with active motions must be in the neutral
position (inactive) to enable the transmitter.
5. Turn the ON/OFF key ON (clockwise) to enable the transmitter.
6. Pull out the Stop Button. The LED should pulse green telling you the
transmitter is ready for use.
Note: If you find that the Stop Button is already pulled out, you must push it in and
then pull it out again. This sequence permits proper operation of the Stop
circuit. If the unit has experienced a time-out auto-disconnect, it is not
necessary to repeat the Stop Button procedure; instead, push and hold the
START Button for one (1) second.
7. Press and hold the START Button. This activates the warning/start
alarm if one is installed on the crane/machine and indicates to you the
receiver is under your control.

Battery Level Monitor). If the Stop Button is pushed during the time the LED is flashing,
all control functions immediately cease and the transmitter will not start again until a
fresh battery is installed. It is recommended to put the machine you are controlling in a
safe state or safe place during this five minute warning so that it will not pose a hazard
while you are changing the exhausted battery with a fully charged battery.
CAUTION
If the STOP button is pushed during the time the LED is indicating an
imminent shutdown, be aware that the transmitter will not restart until a
fresh battery is installed. Be sure to place the machine your are
controlling in a safe state or place during the warning period so that it
does not pose a hazard while the battery is being changed.
Under normal duty cycles, you can expect approximately 10 to 16 hours (cumulative) of
actual usage before a battery is exhausted and needs to be recharged. An exhausted
battery will take approximately 12 hours to become fully charged.
Note: A battery can be left on the charger for extended periods of time without
damage to either the battery or the charger.

3.2 CB70 Battery Charger
The CB70 battery charger, Figure 3, has two charging compartments that can
simultaneously charge two batteries. Battery types BT06K (TM70 transmitter battery)
BT06, BT12, and BT20K can be charged in any combination using the charger.
Figure 3. CB70 Battery Charger
Note: The Charging LED lights when the battery is first seated in the cradle
indicating the battery is properly seated and is charging. The Charging LED
goes out after when the battery is charged.
1. Connect the charger to the proper power source using adaptor supplied
for your system.
When installing the battery charger, bear in mind that the batteries must be charged at
temperatures over 41ºF (5ºC) and that the power supply must be left for the entire time
that it takes to charge, without interruption. Also remember that the charger must not be
left in direct sunlight as the batteries will not become fully charged at temperatures
exceeding 95ºF (35ºC).
2. Place the batteries in the charger. The LED’s should illuminate indicating
that recharging is in process. Complete recharging takes 12 hours.
Batteries may remain in the charger for an unlimited period of time after
they are fully charged.
If the LED does not illuminate when the battery is seated for charging, there is an
improper connection. Remove the battery from the charger, check that the terminals are
clean and unobstructed, and reseat the battery firmly in its cradle; check to see that the
LED is on. Should this fail, contact Cervis Customer Support.
The capacity of the batteries decreases with use. Their life span is estimated to be 500
recharging cycles, but this depends largely on the conditions of use, for which the
following is recommended:
CAUTION
Only use batteries certified by Cervis. When the batteries are
exhausted, they should be safely disposed of or recycled
according to local regulations.
