Laser safety

This product uses the invisible laser beam to communicate. This product is manufactured and sold in 
accordance with “Performance Standards for Light-Emitting Products” (FDA/BRH 21 CFR 1040) or “Radiation 
Safety of Laser Products, Equipment Classification, Requirements and User’s Guide” (IEC Publication 60825-
1) provided on the safety standards for laser beam.
As per the said standard, this product is classified as “Class 1 (I) Laser Products”. 
This is simple a product to operating that is not required to training from a “Laser safety officer”.
In case of any failure, do not disassemble the instrument. Contact TOPCON or your TOPCON dealer.

TS/IS/QS series

The software must be of the correct version for your version of the TS/IS/QS series, otherwise the RC-4 will not 
function properly. Contact TOPCON or your TOPCON dealer for version information.

Do not use the battery or charger for any other equipment or purpose. Fire or burns caused by 
ignition could result.

To prevent shorting of the battery in storage, apply insulating tape or equivalent to the terminals. 
Otherwise shorting could occur, resulting in fire or burns.

To reduce the risk of hazards, use only CSA/UL certified power supply cord set, cord is Type SPT-
2 or heavier, minimum No.18 AWG copper, one end is provided with a moulded-on male 
attachment plug cap (with a specified NEMA configuration), and the other end is provided with a 
moulded-on female connector body (with a specified IEC non-industrial type configuration).

Do not use batteries or the battery charger if wet. Resultant shorting could lead to fire or burns.

Do not connect or disconnect power supply plugs with wet hands. Electric shock could result.

Do not use batteries other than those designated. An explosion could occur, or abnormal heat 
generated, leading to fire.

Caution

Do not touch liquid leaking from batteries. Harmful chemicals could cause burns or blisters.

Warning

Do not use within the vicinity of hospitals. Malfunction of medical equipment could result.

Use the instrument at a distance of at least 22 cm from anyone with a cardiac pacemaker. 
Otherwise, the pacemaker may be adversely affected by the electromagnetic waves produced 
and cease to operate as normal.

Do not use onboard aircraft. The aircraft instrumentation may malfunction as a result.

Do not use within the vicinity of automatic doors, fire alarms and other devices with automatic 
controls as the electromagnetic waves produced may adversely affect operation resulting in an 
accident.

Warning

Use of controls or adjustments or performance of procedures other than those specified herein 
may result in hazardous radiation exposure.
