Safety warnings

Persons with cardiac pacemakers are generally advised not to use radio sets! No transmission in immediate proximity to persons with cardiac pacemakers.

Do not touch the antenna during the transmission, do not hold it close to your body, especially not close to the face or the eyes. When using a headset be sure not to turn the volume of your radio set too high: otherwise the noise might damage your hearing.

Do not operate the radio sets neither in an aircraft nor in a hospital or in comparable facilities. Switch off the radio set, if you are in explosive-prone environment (e.g. petrol station). Make sure not to change the battery packs in those places.

When using the radio set in a vehicle be sure to comply with the national regulations! In some countries it is forbidden to use a radio set while driving a vehicle! In a vehicle equipped with an airbag you must not operate or store the radio set neither directly above the airbag nor in the inflation zone of the airbag.

Never open the housing of a radio set or its accessories and do not carry out any modification. Ensure that any repair is carried out exclusively by qualified personnel. Modifications of or interventions in the radio set automatically lead to an expiry of the type approval, moreover it voids all warranty claims.

Prevent children from playing with the radio set, accessories or the packing material!

If you state the odor emissions or the formation of smoke, immediately switch off the radio set and remove the battery packs. Do not operate the radio set, if you detect any damage of the housing or the antenna. Contact a qualified workshop.

Protect your radio sets and the accessories against strong vibrations and extreme temperatures (avoid operating temperatures below -10°C or above +40°C). Do not expose the radio set to direct sunlight for a prolonged period (e.g. shelf in the vehicle).

The charger and the power supply unit must be protected against humidity/moistness.

Never throw the battery packs into the fire! Never short-out the contacts of the battery packs!

Important information/Intended use

stabo freecomm 400 II is a PMR 446 handheld radio set for voice radio over short distances.

The radio standard PMR 446 is assigned in AT, BE, CH, DE, DK, ES, FI, FR, GB, GR, IE, NL, NO, PL, PT, SI (free of charge and without any registration). There is obligatory registration in IT: Italian residents have to pay a nonrecurring charge upon registration of the radio set! (Tourists may use their radio sets free of charge for the duration of their stay in Italy.)

For information on national regulations concerning the use of radio sets on travels abroad please contact the embassies/consulates of the corresponding countries or you may get the information from the corresponding telecoms and postal regulator.

PMR 446-radio sets transmit/receive on 16 specified channels (446 MHz). Within the radius of reach you can communicate via an optional number of radio sets, however, only one person can talk and the other/s listen. Uncoded voice radio links are not confidential!

The range is a function of many factors. Apart from the statutory transmitting power other factors are relevant: e.g. the position of the antenna (it should be installed at right angle and send freely), the energy supply (fully charged battery packs fully exploit the reach) and above all the environment where you transmit. Each “obstacle” (hills, buildings, trees) reduces the range, some materials (e.g. reinforced concrete, pieces of rock) give rise for considerable screening effects. Under optimum conditions (e.g. during sailing or paragliding) PMR 446 radio sets have a maximum reach of 10 km. In housing areas a range of 1 – 2 km is realistic, in strongly screened environment (e.g. in the mountains or inside buildings made of reinforced concrete) the reach may drop to a few hundred meters or less.
