5. Do not:
a) Recharge non-rechargeable batteries.
b) Force discharge, recharge or disassemble batteries.
c) Do not expose batteries to temperatures below -5 ° C (23 ° F) or above 60 ° C
(140°F), as this may cause leakage or explosion resulting in burns or injury.
6. Ensure batteries are installed correctly, following indicated polarity (+ and -).
7. Do not mix old and new batteries, different brands, or different battery types
(e.g., alkaline, carbon-zinc, or rechargeable).

store them properly.
9. Do not dispose of batteries in household trash or incinerate.
10. The performance of the radio system may be affected when used near devices
with strong magnetic fields or metallic surfaces. Structural conditions may also
impact range and functionality.
11. Do not operate the radio system in areas prone to high interference, such as
hospitals, airports, or other sensitive facilities.
