regards to safety.
Although the F22 transmitter is very durable and weather resistant care should
be taken not to expose it to severe impact or pressure.
During operation, if the power supplied from transmitter’s batteries is
insufficient, the transmitter will send out EMS signal first to de-energize all of
motion relays inside the receiver to stop crane’s moving (Notice: the motions
which are set as ”Bypass EMS” will continuously move.), and then the LED
indicator and buzzer on transmitter will light and sound continuously. At this
time, need to be replaced with AA size alkaline batteries. All four batteries
should be replaced at the same time. Don’t use manganese-zinc batteries
because of their corrosive properties.
If the severe interference occurred you should stop using the equipment at
once.

Self-Diagnostics
In order to simplify the maintenance, this remote control system has been
designed with the built-in self-diagnostics circuit in the transmitter and receiver.
As long as the micro control unit is in proper working condition, malfunctions
in pushbutton, joystick, RF circuit, relay and relay driver circuits (including
relay coil and relay contact) can be detected. When malfunction occurs,
24
transmitter or receiver will generate a simple and clear alarm. Not only the
operator and maintenance personnel can fully understand the condition of
remote controller, but can also reduce the maintenance time by following the
error message for repair.
Note:
1. Malfunction alarm mode can be set by dip switch “SW8” in the “Receiver/
Decoder” module for the Simple Alarm Mode or Morse Alarm Mode.
Simple Alarm Mode was discussed in Operator’s Manual. The following
explains the “Morse mode” for the error message.
2. Alarm (error message) is shown according to Morse code. “ ” Indicates
short alarm for a duration of 0.26 second; “ ” indicates long alarm for a
duration of 0.78 second; interval between alarms is 0.26 second. An
example for transmitter pushbutton error message is shown as follows:
“
”
0.26 sec 0.26 sec 0.78 sec
1.5 sec
3. When an error message is detected by receiver or transmitter’s selfdiagnostics, an alarm will sound and “Power-OFF’ will be activate. Unless
the malfunction has been corrected, it will be impossible to Power-On the
controller.
4. Technicians for maintenance can use error message. However, we
recommend the technician replace only the module. The defective module
should be returned to our distributor for the repair of components. This
will eliminate further damage to the controller.
5. If you do not understand the error message from the transmitter or receiver,
or the signal is not listed in this manual, please contact our distributor for
clarification and recommendation.

Note:
1. When receiver’s self-diagnostics detects a malfunction, alarm will continue, unless
the malfunction has been corrected or the power to the receiver has been
disconnected.
2. The receiver can be set by the software to alarm or not, when error occurred
relating to item 20 ~ 21.
3. The receiver can be set by software to close the relative action (i.e. “Relay-Off”) or
“Power-Off” automatically, when the error occurred relating to items 20 ~ 22. In
the other items, the receiver will enter into the Auto Power-Off mode.
4. This receiver contains Auto Gain Control circuit with high sensitivity; when not in
operation, it may receive weak signal from unknown sources. As long as the
interference does not occur very often, it will not affect the normal operation. No
frequency change is necessary.
