2 Cautions and Warnings
Cautions:
• Only use a certified charger/cord with an output of 5 V (dc) ±5%, 1 A ±5%.
• Keep the device out of extremely high or low temperature locations.
• Do not expose the battery to liquid.
• Do not use the device if you notice any damage to the battery.
• Do not disassemble or modify the battery.
• Handle and dispose of the battery per local regulations.
• If the recharging operation fails to complete, even when the specified recharging
time has elapsed, immediately stop further recharging.
• Do not leave the battery unattended while charging.
• Unplug the charger when the battery is fully charged.
• Improper use or disposal of lithium ion batteries can cause a fire.
• This instrument is not intended for use in flammable environments.
WARNING
This symbol is used to alert the user to the presence of important operating
and maintenance (servicing) instructions in the literature accompanying this
instrument.
WARNING
Exposure to high concentrations of CO2 or refrigerants is dangerous and can
be life-threatening.
The instrument is not for use in toxic or hazardous environments. It is not a personal
protection or life-saving device. Always exercise extreme caution in potentially toxic or
hazardous environments.

To achieve optimal performance and the specified sensitivities, it is recommended to
allow D-TEK Stratus to run for 15 minutes prior to use.

The upper leak detection limit is not specified by INFICON as there is no upper limit
to the size of the leak the detector is able to detect.

As no 50 g/yr. leak standard was available during testing, a 32 g/yr leak standard was
substituted.
SAE standards J2791 (R-134a) and J2913 (R-1234yf) specify sensitivity to the
