WARNING Read all safety warnings and all instructions, including the information on the bottom side of the construction site radio. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all safety warnings and instructions for future reference.

The term “construction site radio” used in the safety notes, refers to mains-powered construction site radios (with mains cable) and to battery-operated construction site radios (without mains cable).

▶ Keep work area clean and well lit. Cluttered or dark areas invite accidents.
The plug of the construction site radio must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) construction site radios. Unmodified plugs and matching outlets will reduce the risk of electric shock.
▶ Do not misuse the cord to carry the construction site radio, hang it up, or for pulling the plug out of the outlet. Keep the cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating the construction site radio outdoors, only use extension cords suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
When operating the construction site radio in damp environments is unavoidable, use a residual current device (RCD). The use of a residual current device (RCD) reduces the risk of electric shock.
▶ Connect the construction site radio to a mains supply that is properly connected to earth. Socket and extension cord must have an operative protective conductor.

▶ Do not expose the construction site radio to rain or wet conditions. Water entering a construction site radio will increase the risk of electric shock.
- Keep the construction site radio clean. Contamination may result in danger of electric shock.
▶ Check the construction site radio, cord and plug each time before using. Do not use the construction site radio when defects are detected. Do not open the construction site radio yourself and have it repaired only by qualified personnel using original spare parts. Damaged construction site radios, cords and plugs increase the risk of electric shock.
▶ Completely unwind the mains cable when operating the construction site radio via mains supply. Otherwise the mains cable can heat up.
▶ Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e.g., against continuous intense sunlight, fire, water, and moisture. Danger of explosion.
When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
▶ Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
▶ Only use the battery in conjunction with your construction site radio and/or a Bosch power tool. This is the only way to protect the battery against dangerous overload.
