Preparation; Initial Operation - Bosch GLR500 Mode D'emploi

A) The working range increases depending on how
well the laser light is reflected from the surface of
the target (scattered, not reflective) and with
increased brightness of the laser point to the
ambient light intensity (interior spaces, twilight). In
unfavorable conditions (e.g. when measuring
outdoors at intense sunlight), it may be necessary
to use the target plate.
B) In unfavorable conditions (e.g. at intense
sunlight or an insufficiently reflecting surface), the
maximum deviation is ±20 mm per 150 m (±0.8 in
per 492 ft). In favorable conditions, a deviation
influence of ±0.05 mm/m (±0.0006 in/ft) must be
taken into account.
Inserting/Replacing the Battery
Use only alkali-manganese or rechargeable
batteries.
Fewer measurements are possible when using
1.2 V rechargeable batteries as compared with
1.5 V batteries.
To open the battery compartment 22, turn the
locking knob 23 to position
battery compartment.
When inserting the batteries/rechargeable
batteries, pay attention to the correct polarity
according to the representation on the inside of
the battery compartment.
When the battery
time on the display, at least 100 individual
measurements are still possible. The continuous
measurement mode is deactivated.

INITIAL OPERATION

• Protect the rangefinder against moisture and
direct sun irradiation.
• Do not expose the rangefinder to extreme
temperatures or variations in temperature.
Switching On and Off
To switch on the rangefinder, the following
possibilities are given:
– Pressing the On/Off button 16:
The rangefinder is switched on and is in length
measurement mode. The laser is not activated.
– Briefly pressing the measuring button 7:
Rangefinder and laser are switched on. The
rangefinder is in length measurement mode.
– Pressing the measuring button 7 for several
seconds: Rangefinder and laser are switched
on. The rangefinder is in continuous
measurement mode.

C) In the continuous measurement function, the
maximum operating temperature is +40 °C
(104 °F).
D) Fewer measurements are possible when using
1.2 V rechargeable batteries as compared with
1.5 V batteries.
Please observe the article number on the type
plate of your rangefinder. The trade names of the
individual rangefinders may vary.
The rangefinder can be clearly identified with the
serial number 20 on the type plate.

Preparation

When the battery symbol
batteries/rechargeable batteries must be
replaced. Taking measurement is no
longer possible.
Always replace all batteries at the same time.
Only use batteries from one brand and with the
identical capacity.
• Remove the batteries/rechargeable batteries
from the rangefinder when not using it for
longer periods. When storing for longer
periods, the batteries/rechargeable batteries
can corrode and discharge themselves.
INSTALLING HAND STRAP
Feed string loop on end of hand strap 29 under
hand strap mounting post 17 and pull out on other
side. Feed hand strap 29 through string loop end
and pull tight.
Operation
WARNING
persons or animals and do not look into the
laser beam yourself, not even from a large
distance.
To switch off the rangefinder, press the On/Off
button 16 for a few seconds.
To save the batteries, the rangefinder switches off
automatically after approx. 5 minutes when no
measurement is carried out.
When switching off automatically, all stored
values are retained.
Measuring Procedure
After switching on, the rangefinder is always in
length measurement or continuous measurement
mode. Other measuring modes can be switched
to by pressing the respective mode button (see
"Measuring Modes", page 11).
After switching on, the rear edge of the
rangefinder is preset as the reference level for the
measurement. By pressing the reference level
