DAILY MAINTENANCE

We are not responsible for any damage, malfunction or trouble,
whether direct or indirect, caused by the use of our product. Please
be fully aware of this before using our product.

This product has been designed for private or industrial use only. It
is not for use in situations where strict safety precautions are
necessary such as in connection with medical equipment, whether
directly or indirectly.

To prevent damage to the unit from static electricity, remove static
electricity from your body by touching metal around you (door knob,
window frame) before touching the unit.

Static electricity may cause not only damage to the unit, but may cause breaks in or
a loss of data.

Use these units under conditions with an ambient temperature of

-10 to 60Ɏ .

The RTR-61 only becomes water resistant (IP64 splash resistant) if
the temperature sensor has been connected.

Without the sensor connected, the connector part of neither the main unit nor the
temperature sensor is water resistant; make sure not to get wet.

Do not expose the unit to harmful gases or chemicals.

It may cause corrosion and/or other danger to the unit and to people handling the
unit.

Do not drop the unit, or expose the unit to a strong impact. If that
happens to the unit, immediately remove the batteries and stop
using.

Continued use may cause fi re or electrocution.

Battery terminals may provide insuffi cient contact due to age or
vibration.

This may lead to data loss.

Battery life depends on the measurement environment,
communication frequency, recording interval and battery quality.

If the unit will not be used for period of time, for safety reasons
please remove the battery.

If left in the unit, it may leak and lead to malfunctioning.

Do not use or store the unit in places such as listed below:

-Areas exposed to direct sunlight

-Areas exposed to water or high-pressure water fl ow.

-Areas exposed to organic solvents and corrosive gas.

-Areas exposed to strong magnetic fi elds

-Areas exposed to static electricity.

-Areas exposed to fi re or overheating.

-Areas exposed to excessive dust or smoke.

Please be careful when using in extreme
hot or cold environments; touching the
unit may cause burns or frostbite.

If the unit gets dirty, wipe it with a clean
cloth dipped in alcohol; DO NOT WASH
with WATER.
NEVER use an acid, alkaline, or chlorine
based detergent. This will cause harm to
the electric components in the unit.

CAUTION

What is RTR-61?

ɜ Ther mo Recorder Push Wireless RTR-61 is a handy-type device which acts both as a thermometer and a

temperature recorder, which has been designed to easily measure and record the internal temperature of
food items and liquid temperature using a needle-type sensor.

ɜ This product has been designed to meet IP64 standards (splash resistant; rated for use in daily life).

RTR-61 measures and records core temperature, which makes it suitable for use in the food production
industry especially temperature management for HACCP.

ɜ The unit incor porates a battery life warning function, which informs the user when it is time to replace the

battery. When the battery power becomes low, all normal operations will stop in order to protect the data.

ɜ The LCD Backlight allows the display to be easily read even in low light. The LCD contrast can also be

easily adjusted for better viewing.

ɜ These units are also designed with shor t range wireless functions that when coupled with our exclusive

software set "Push Wireless Communication Set (RTR-61SK)", makes it possible to carry out wireless
communication, allowing for easy and effective management of multiple RTR-61 units.

(Measuring in progress and waiting for the constant temp)

Do not remove the sensor while "Wait for Temp" is on display
and the PUSH Record LED is blinking.

- When the "Wait for Constant Temp Function" is active, the temperature will not be

be performed and you will be returned to the Top Window.

- If the Button Sound has been set to "ON", the unit beeps both when the "Wait for
