Starting Operation Of The Remote Control; Starting Operation Of The Rotary Laser - Bosch GRL 250 HV Professional Notice Originale

24 | English
Insert the charging connector (20) of the charger into the
charging socket (17) of the battery pack (13). Connect the
battery charger to the mains supply.
Charging the empty battery pack takes approx. 14 hours.
The charger and battery pack are protected against over-
charging.
A battery that is new or has not been used for a longer period
does not develop its full capacity until after approx. 5 char-
ging/discharging cycles.
Do not recharge the battery pack (13) after each use, as this
will reduce its capacity. Recharge the battery pack only
when the battery warning (12) flashes or lights up continu-
ously.
A considerably reduced operating period after charging in-
dicates that the battery pack is used up and must be re-
placed.
If the battery pack is empty, the measuring tool can also be
operated using the charger (18) when connected to the
mains supply. Switch the measuring tool off, charge the bat-
tery pack for approx. 10 minutes and then switch the meas-
uring tool on again with the battery charger connected.
To change the battery pack (13), turn the locking
mechanism (16) to position and pull the battery pack out
of the measuring tool. Push a new battery pack into the
measuring tool and turn the locking mechanism (16) to posi-
tion .
Take the battery pack out of the measuring tool if you
u
do not intend to use the tool for a long time. Batteries
can corrode or self-discharge during prolonged storage in
the measuring tool.
Operation with batteries/rechargeable batteries
It is recommended that you use alkaline manganese or re-
chargeable batteries to operate the measuring tool.
To remove the battery compartment (14), turn the locking
mechanism (15) to position . Pull the battery compart-
ment out of the measuring tool and insert the non-re-
chargeable/rechargeable batteries.
When inserting the batteries, ensure that the polarity is cor-
rect according to the illustration on the inside of the battery
compartment.
Always replace all the batteries at the same time. Only use
batteries from the same manufacturer and which have the
same capacity.
Slide the battery compartment (14) into the measuring tool
and turn the locking mechanism (15) to position .
Take the batteries out of the measuring tool when you
u
are not using it for a prolonged period of time. The bat-
teries can corrode and self-discharge during prolonged
storage in the measuring tool.
Charge-control indicator
When the battery warning (12) flashes red for the first time,
the measuring tool can still be operated for approx. 2 hours.
When the battery warning (12) lights up red continuously,
no further measurements can be taken. The measuring tool
switches off automatically after 1 minute.

Operation
Protect the measuring tool and remote control against
u
moisture and direct sunlight.
Do not expose the measuring tool or remote control to
u
any extreme temperatures or variations in temperat-
ure. For example, do not leave them in a car for extended
periods of time. In case of large variations in temperature,
allow the measuring tool and the remote control to adjust
to the ambient temperature before putting them into op-
eration. Before continuing work with the measuring tool,
always perform an accuracy check (see "Accuracy Check
of the Measuring Tool", page 26).
The precision of the measuring tool may be compromised
if exposed to extreme temperatures or fluctuations in
temperature.
Avoid substantial knocks to the measuring tool and
u
avoid dropping it. Always carry out an accuracy check
before continuing work if the measuring tool has been
subjected to severe external influences (see "Accuracy
Check of the Measuring Tool", page 26).

Starting Operation of the Remote Control

When pressing the operating controls, it is possible to bring
the measuring tool out of its level position, so that the rota-
tion is briefly interrupted. This effect is avoided when using
the remote control.
The remote control remains ready for operation as long as a
battery with sufficient voltage is inserted.
Set up the measuring tool in such a manner that the signals
of the remote control can directly reach one of the
sensors (7). If the remote control cannot be pointed directly
at a sensor, the working range will be reduced. By reflecting
the signal (e.g. against walls), the working range can be im-
proved even for indirect signals.
After pressing a button on the remote control, the signal
transmission indicator (31) will light up, indicating that a sig-
nal has been sent out.
It is not possible to switch the measuring tool on/off with the
remote control.

Starting Operation of the rotary laser

Keep the work area free from obstacles that could re-
u
flect or obstruct the laser beam. For example, cover
any reflective or shiny surfaces. Do not measure
through panes of glass or similar materials. The meas-
urements may be distorted by a reflected or obstructed
laser beam.
