Safety Notes

WARNING
Read all safety warnings and all instructions, including the information on the rear 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 power supply plug) and to battery-operated construction site radios (without power-supply plug).

  • Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.

  • The main plug of the power-supply plug must match the socket outlet. Never modify the plug in any way. Do not use adapter plugs together with construction site radios.  Unmodified plugs and matching outlets will reduce the risk of electric shock.

  • Do not misuse the cord of the power-supply plug to carry the construction site radio charger, 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.

  • Completely unwind the connection cable of the power supply plug when operating the construction site radio via the mains supply. Otherwise, the connection cable can heat up.

  • Take care that the main plug can be pulled at any time. The mains plug is the only possibility to disconnect the construction site radio from the mains supply.
    ****Protect the construction site radio from rain and moisture. The penetration of water into the construction site radio increases the risk of electric shock.

  • Keep the construction site radio and the power-supply plug clean. Contamination may result in the danger of electric shock.

  • Check the construction site radio, power-supply plug, cable, and plug each time before using. If damage is detected, do not use the construction site radio. Never open the construction site radio or the power-supply plug yourself, and have repairs carried out only by a qualified repair person using only identical replacement parts. Damaged construction site radios, power supply plugs, cables, and plugs increase the risk of electric shock.

  • This construction site radio can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the construction site radio in a safe way and understand the hazards involved. Otherwise, there is a danger of operating errors and injuries.

  • Supervise children. This will ensure that children do not play with the construction site radio.

  • Cleaning and user maintenance of the construction site radio shall not be made by children without supervision.

  • Do not open the battery. The danger of short-circuiting.
    Protect the battery against heat, e.g., against continuous intense sunlight, fire, water, and moisture. The danger of explosion.

  • When the 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.

  • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritations or burns.

  • In case of damage and improper use of the battery, VA- pours may be emitted. Ventilate the area and seek medical help in case of complaints. The vapors can irritate the respiratory system.

  • 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

  • Use only original Bosch Professional 10.8 V lithium-ion batteries. When using other batteries, e.g. imitations, reconditioned batteries, or other brands, there is a danger of injury as well as property damage through exploding batteries.

Assembly

Power Supply of the Construction Site Radio
The power supply of the construction site radio can take place via the power- supply plug 24 or via a lithium-ion battery 15.
Operation with Battery Pack
▶ Use only original Bosch Professional 10.8 V lithium-ion batteries. Using other batteries can lead to injuries and pose a fire hazard.
Note: The use of batteries not suitable for the construction site radio can lead to malfunctions of or cause damage to the construction site radio.
Note: The battery pack is supplied partially charged. To ensure the full capacity of the battery pack, completely charge the battery pack in the battery charger before using it for the first time.
▶ Use only the battery chargers listed on the accessories page. Only these battery chargers are matched to the lithium-ion batteries used in your construction site radio. The  Lithium-Ion battery can be charged at any time without reducing its service life. Interrupting the charging procedure does not damage the battery.
The battery is equipped with an NTC temperature control which allows charging only within a temperature range of between 0 °C and 45 °C. A long battery service life is achieved in this manner. Insert a battery into the battery port 17 in such a manner that the connections of the battery face against the connections in the charging compartment  17, and allow the battery to engage in the battery port.
The battery charge-control indicator b appears on the display as soon as a battery pack with sufficient voltage is inserted and the construction site radio is not connected to the mains supply via the power-supply plug 24.
The battery charge-control indicator b indicates the current battery pack status. When the battery charge-control indicator flashes,  the battery pack must be charged.
