FOREWORD

Thank you for purchasing the TOPCON LS-B4 Laser Sensor.
For superior product performance, please read these instructions carefully and keep them
in a convenient place for future reference.

GENERAL HANDLING PRECAUTIONS

Before starting work or operation, be sure to check that the system is functioning properly.

Guarding the instrument against shocks.

When transporting the instrument, provide some protection to minimize risk of shocks.
Heavy shocks may cause faulty measurement. When carrying this instrument, hold the
hand grip.

Protecting the instrument from sudden temperature changes.

Any sudden change in temperature of the instrument may result in a reduction of the
measuring range. When taking the instrument out from a heated vehicle, let it acclimate
itself to the ambient temperature.

Checking battery power.

Before operating, check remaining battery life.

from a water hose. The inside of the instrument will be damaged by the water.
This instrument is designed based on the International Standard IPX 6, but it is not
protected from a high pressure water stream or submergence.

Cleaning

Always clean the detector. The dust may cause faulty measurement.

Affection of the radio waves

When using the instrument in the following place, the strong radio wave may cause faulty
operation.

• Near the instrument occurring strong radio waves. (e.g.Transceiver)

• Near the radio wave towers such as television or radio.

Green ON :Charging completed.
Green flashing :BT-54Q isn‘t installed on DB-54C correctly.
Red flashing :Indicates rechargeable battery protection feature* is active. See note

on next page for proper charging conditions.

*Battery protection feature:
In case of overcharge or high or low ambient temperatures that exceeds charging temperature range, charg­ing will be stopped or changed to protect battery.

•You can charge the battery pack(BT-54Q) while the battery holder(DB-54C) is installed on the
instrument(LS-B4).

•Dry batteries (two D-cell alkaline) can be used by removing the battery pack (BT-54Q) and placing

2 PREPARING FOR USE

Note

•Recharging should take place in a room with an ambient temper ature range of 10°C to 35°C (50°F
to 95°F).

•Exceeding the specified charging time ma y shorten the life of the battery and should be av oided if
possible.

•The battery source will discharge when stored and should be checked before using with instru­ment.

•Be sure to charge a stored battery source every 3 or 4 months and store in a place at 30 °C (86 °F)
and below when it will not used for a long period.
If you allow the battery to be completely discharged, it will have an effect on the overall perfor­mance for proper charging in the future.

•Recharging can take less than 9 hours depending on the discharge condition of the battery when
charging begins.

2 PREPARING FOR USE

Before connecting any cable to the input/output external connector of this instrument,
remove the batteries (dry batteries or chargeable battery pack).
If a cable is connected to the input/output external connector and the power is turned on
while the batteries are installed, “Double power supply connection warning” is displayed
(refer to “2.3.2 Double power supply connection warning”). Immediately turn off the
power and remove the batteries from the battery holder. Replace the empty battery
holder. Then, turn on the power again.

Do not use the LS-B4 without the battery cover or battery holder installed.

Without it installed, water may enter the instrument and cause a malfunction.

If the LS-B4 battery status light (Mode 1 indicator) blinks, replace the batteries with
new ones or charge the battery pack.

Rotating Laser (RL Battery Status Light)*

If the rotating laser battery status light (Mode 2 indicator) blinks it indicates that the
laser batteries are running low. Replace or charge the rotating laser batteries.
*The rotating laser battery status light works only with specific Topcon rotating laser

models that are equipped with a sensor-detectable low battery alert function.
