2.2 GENERAL
Radio controlled material handling equipment operates in several directions. Cranes, hoists, lifting devices and
other material handling equipment can be large, and operate at high speeds. Quite frequently, the equipment is
operated in areas where people are working in close proximity to the material handling equipment. The operator
must exercise extreme caution at all times. Workers must constantly be alert to avoid accidents. The following
recommendations have been included to indicate how careful and thoughtful actions may prevent injuries,
damage to equipment, or even save a life.
2.3 PERSONS AUTHORIZED TO OPERATE RADIO
CONTROLLED CRANES
Only properly trained persons designated by management should be permitted to operate radio controlled
equipment.
Radio controlled cranes, hoists, lifting devices and other material handling equipment should not be operated by
any person who cannot read or understand signs, notices and operating instructions that pertain to the equipment.
Radio controlled equipment should not be operated by any person with insufficient eyesight or hearing or by any
person who may be suffering from a disorder or illness, is taking any medication that may cause loss of
equipment control, or is under the influence of alcohol or drugs.

operate the material handling equipment if the direction of travel or function engaged does not agree
with what is indicated on the controller
use the crane, hoist or lifting device to lift, support or transport people
lift or carry any loads over people
operate the crane, hoist or lifting device unless all persons, including the operator, are and remain clear
of the supported load and any potential pinch points
operate a crane, hoist or lifting device when the device is not centered over the load

WARNING
THE OPERATOR SHOULD NOT ATTEMPT TO REPAIR ANY RADIO CONTROLLER. IF ANY PRODUCT
PERFORMANCE OR SAFETY CONCERNS ARE OBSERVED, THE EQUIPMENT SHOULD IMMEDIATELY BE
TAKEN OUT OF SERVICE AND BE REPORTED TO THE SUPERVISOR. DAMAGED AND INOPERABLE
RADIO CONTROLLER EQUIPMENT SHOULD BE RETURNED TO MAGNETEK FOR EVALUATION AND
REPAIR. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS INJURY OR DEATH AND
DAMAGE TO EQUIPMENT.
2.5 TRANSMITTER UNIT
Transmitter switches should never be mechanically blocked ON or OFF. When not in use, the operator should
turn the transmitter OFF. A secure storage space should be provided for the transmitter unit, and the transmitter
unit should always be placed there when not in use. This precaution will help prevent unauthorized people from
operating the material handling equipment.
Spare transmitters should be stored in a secure storage space and only removed from the storage space after the
current transmitter in use has been turned OFF, taken out of the service area and secured.
2.6 PRE-OPERATION TEST
At the start of each work shift, or when a new operator takes control of the crane, operators should do, as
a minimum, the following steps before making lifts with any crane or hoist:
Test all warning devices.
Test all direction and speed controls.
Test the transmitter emergency stop.
2.7 BATTERIES
WARNING
KNOW AND FOLLOW PROPER BATTERY HANDLING, CHARGING AND DISPOSAL PROCEDURES.
IMPROPER BATTERY PROCEDURES CAN CAUSE BATTERIES TO EXPLODE OR DO OTHER SERIOUS
DAMAGE. FAILURE TO FOLLOW THIS WARNING COULD RESULT IN SERIOUS INJURY OR DEATH AND
DAMAGE TO EQUIPMENT.

4. Function Settings
4.1 Transmitter
4.1.1 Enter Function Setting Mode
1) Press down the STOP button.
2) Open the battery cover.
3) Set dip position #10 to “1” or ON position.
4) Reset the STOP button (transmitter power on).
5) Entered Function Setting Mode.
6) Status LED displays firmware version.
4.1.2 Channel Settings
1) After entering the Function Setting Mode (refer to section
4.1.1 Enter Function Setting Mode).
2) Press and hold PB3 for up to 1 second to enter the
Channel Setting Mode (Status LED blinks orange).
3) Release PB3 (Status LED displays current channel). A
green blink represents the tens (+10) and a red blink
represents the units (+1). For example, 1 green blink
followed by 5 red blinks is channel 15.
4) Press PB1 to increment the units (+1) and PB2 to
increment the tens (+10). For example, press PB2 two
times and then PB1 four times is channel 24. When finished the transmitter Status
LED will display the newly selected channel.
5) Transfer the newly selected transmitter channel to the receiver by press and hold
PB3 for up to 10 seconds or until the Status LED turns off; the transferring process
is completed. Make sure the receiver power is turned on during the entire process.
Skip step 5 if changing receiver channel is not required or needed.
6) Exit Function Setting Mode by pressing down the STOP button and set the dip
position #10 back to “0”or OFF position.
7) Reset the STOP button and then press the START button to resume operation.
Note : When selecting a new channel make sure each button press do not exceed 3 seconds.
Important Note:
Step 5 illustrated above is strictly required if you are changing the entire system channel (both
transmitter and receiver). If you exit the Channel Setting Mode without pressing PB3 for up to
10 seconds to transfer the newly selected channel to the receiver then the system channel will
no longer match (new transmitter channel vs. old receiver channel). In this case you would
have to change the newly selected transmitter channel back to its previous setting by reentering
the Function Setting Mode and then press and hold PB1 and PB3 at the same time for up to 2
seconds; this will reset the newly selected transmitter channel back to its previous setting. Or
perform section 4.1.3 Receiver-to-Transmitter Pairing process; this will transfer the receiver
channel to the transmitter. Then repeat the channel setting process if you would like to select a
new channel.

4.2 Receiver
4.2.1 Channel Settings
Set the receiver channel by configuring the channel
dipswitch located on the RF/decoder board, only the first 6
dip positions are used for channel programming. The
system channels table on section 4.2.7 illustrates which
dipswitch setting corresponds to which channel. Once the
receiver channel is altered do make sure to change the
transmitter channel as well. The channel on both transmitter
and receiver must be identical in order for the system to
work (refer to section 4.1.2 Transmitter Channel Settings).
Example:
Top position →“1”
Bottom position →“0”
The above dipswitch setting “1 0 0 1 0 0” corresponds to “channel 36” in the system channels table
on section 4.2.7.
4.2.2 Output Relay Configurations

1. 2 output relays per motion – single speed only
Output relays with Forward (F) and Reverse (R) speed.
2. 3 output relays per motion – shared 2nd speed output relay
Output relays with Forward 1st speed (F1), Reverse 1st speed (R1) and
Forward/Reverse 2nd speed (F/R2). Forward and Reverse 2nd speed (F/R2)
shared the same output relay.
3. 4 output relays per motion – separate 1st and 2nd speed output relays
Output relays with Forward 1st speed (F1), Reverse 1st speed (R1), Forward
2nd speed (F2) and Reverse 2nd speed (R2). Forward and Reverse 2nd speed
with separate output relays.
