WARNING.
Incorrect log-on of the transmitter.
Incorrect transmitter assignment can cause unintended crane
movements by other transmitters. These crane movements can result in
damage or injuries that might be fatal.
After the transmitter is logged on, check to ensure that the crane ID is correctly
assigned between the radio transmitter and radio receiver.

IMPORTANT
Logging-on a DRC-MJ D3 hand-held transmitter, as described in the following,
is a safety-relevant process that must only be performed by authorised and
instructed specialist personnel.
A special technical feature of DRC radio controls is the "wireless log-on
procedure". This log-on procedure enables a DRC radio transmitter to log onto or
log off from a specific DRC radio receiver.
A new transmitter can only log onto a DRC radio receiver that was previously
connected to a DRC radio transmitter if the previously used DRC radio transmitter
is logged off and, in this way, the DRC radio receiver has been enabled.
There are different ways that the DRC radio receiver can be wirelessly released
from the DRC radio transmitter:
• Via the previously logged-on DRC radio transmitter: select '????' in the log-on
menu.
• Via any DRC D3 radio transmitter: enter the crane ID or serial no. of the radio
receiver to be released through a special input menu and send it to the radio
receiver.

NOTE
The transmitter currently logged onto the receiver must be completely
switched off or in Standby mode.
Required steps, see section "7.9.3 Logging-off all radio transmitters" on page 38.
Only released DRC radio receiver are displayed during the transmitter log-on
search process.
A globally unique assignment of the hand-held transmitter to the radio receiver to
be controlled on the crane can be created by logging the DRC-MJ D3 hand-held
transmitter to a DRC radio receiver.
Both DRC-MJ D3 hand-held transmitters as well as DRC radio receivers are
provided with unique address features that are shared during the log-on process
to ensure distinct and unique assignment. During the log-on process, the crane ID
(see sections 6.4.4 and 7.6.3) is also transmitted from the DRC radio receiver to
the DRC-MJ D3 hand-held transmitter and is saved.
DRC-MJ D3 hand-held transmitters display this crane identification/number so that
the operator can identify the controlled crane.
Log-on can be activated in Run mode, STOP mode or Standby mode.
