BATTERIES
The PTR is fitted with a 3 cell rechargeable 3.6V NiMh battery pack. It is NOT user
replaceable. Please return to ThermoWorks for battery replacement. When the PTR
power is low, the 'Lo Bat' segment of the LCD is lit. Print and feed operations are
inhibited when 'Lo Bat' is indicated. Pressing the 'Print' or 'Feed' buttons will result
in 'Recharge' being displayed for a short time in the display.
RECHARGING THE PTR
To recharge the PTR, remove the rubber cap and plug the power cable into the
socket on the right of the instrument. A flashing 'Charging' LED indicates that the
device is being charged.
A slow flashing LED (once/second) indicates normal charging. A fast flash rate
(four times/second) indicates a charging fault (probably the batteries are too cold
to charge). The PTR should only be recharged in an ambient temperature between
41 to 104°F (5 and 40°C).
Charge only with an ThermoWorks PTR power supply - 12V, 3.3A (40 Watt).
Damage may occur if other power supplies are used.
CONNECTING DEVICE TO THE PC
To connect the PTR to a PC, remove the rubber cap and plug the USB cable into the
socket on the left side of the instrument. Use the Printing Thermometer PC software
to customize PTR settings and ticket layout and to download stored reading.
RESET
If the PTR fails to respond, press the 'reset' button on the front of the instrument
which is situated to the left of the display.
CLEANING
Clean only the outside of the instrument with a damp cloth or anti-bacterial wipe.
