3. POWER SUPPLY
ST 40

Cayman is powered by two Li-ion rechargeable batteries (type 18650). 4 batteries
are included in the delivery package. The total run time on one battery charge is from 3 to 4
hours, depending on the modes employed; the most demanding in terms of power consumption
is the AUDIO mode.
The batteries are housed in the battery compartment at the back of the main unit. Battery
replacement is described in 2.1 above.

Cayman monitors its battery charge status. A continuously lit power-on led (4, Fig.
4) on the antenna head means that the battery charge is sufficient. A low battery charge will be
signalled by blinking of the power-on LED and a warning sound. If the charge goes below the
critical threshold, the device will switch off automatically.
Accumulator batteries can be charged with the charger included in the delivery package. The
charging time of a fully discharged battery is 3 hours. As these batteries are free of memory effect,
incomplete charging is acceptable, but the running time will then be shorter.
The following is not allowed:
– long-term storage of discharged batteries
– long-term storage of batteries at low temperatures
– short-circuiting battery contacts
– subjecting batteries to strong shock
– transportation of the device with an installed battery.
4. OPERATING RESTRICTIONS
Use of the device is subject to safety regulations for equipment incorporating UHF
transmitters. The following must be observed at all times:
• Avoid long exposure of people to the antenna beam (the main lobe of the polar diagram) at
distances less than 1m.
• Do not point the antenna at people’s eyes at distances less than 1m.
If the device has been transported at temperatures well outside the service temperature range,
make sure to keep the device indoors at service temperature for 2 hours before use.
