1. Important safety instructions
For the use of the device notice the national safety and accident prevention
regulations and the following safety instructions shown in italics in this instruction
manual.
z Before using CeoTronics products read completely the appropriate operating instructions. If in doubt,
ask our technical staff.
z Use only CeoTronics products without damage and wear.
z If repair work of any kind needs to be done to CeoTronics products, arrange for it to be performed
only by the company CeoTronics or by a specialized workshop that is authorized by CeoTronics. In
all other cases our warranty and liability for the product shall lapse.
z Do not store CeoTronics products outside or in damp ambient conditions. At all times keep them
clean, dry and at normal air humidity. CeoTronics products must not be stored in areas with a
temperature of over +80° C (+176° F), e.g. in the summertime on the parcel shelf of a car. If not
stated otherwise, the following temperature ranges are allowed for CeoTronics products: -10 to
+55° C (+14 to +131° F) for operation, -40 to +80° C (-40 to +176° F) for storage.
z Do not immerse a CeoTronics product into water, if it is not expressly specified for this purpose.
z When using CeoTronics products that are equipped with connection leads ensure that the latter do
not get caught up in operational machinery or wheels!
z CeoTronics products that are not intrinsically safe (explosion-proof) and therefore have no special
explosion-proof designation must never be operated in potentially explosive environments (e.g.
when refuelling cars, aircraft etc.). Devices that are not explosion-proof can unintentionally trigger off
explosions in such areas!
z Connect CeoTronics accessories to a device or disconnect them from a device only when the device
is switched off.
z After switching on the communication system, set the reception volume to approx. 1/2 the available
loudness volume and then test the audible volume, e.g. by opening the squelch on the radio set.
Do not set the volume any higher than is necessary. A very high volume setting can lead to
damaged hearing, particularly if it is continuous. For high volumes or noise levels wear additional ear
plugs. If in doubt, ask your safety officer or company doctor.
