General notes
Please read this manual carefully and completely to make yourself familiar with the vari-
ous functions of your radio set. Make sure to observe the safety instructions to avoid any
danger for you and other persons as well as damage to the radio set. Keep the operating
instructions in a safe place. Be sure to hand over the instructions in case you lend out or
sell the radio sets.
The manufacturer disclaims any liability for damage and consequential damage caused
by the nonobservance of these instructions!
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 sets, if you are in explosive-prone environment (e.g. petrol station). Make sure
not to change the battery pack/the battery 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 sets neither directly above the airbag nor in the
ination zone of the airbag.
Never open the housing of a radio set or its accessories and do not carry out any modication.
Ensure that any repair is carried out by qualied personnel only. Modications 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 sets, accessories, batteries or the packing material.
If you state the odour emissions or the formation of smoke, immediately switch off the radio set
and remove the battery pack/the batteries. Do not operate the radio set, if you detect any damage
of the housing or the antenna. Contact a qualied workshop.

4
Protect your radio sets and the accessories against moistness, heat, dust and strong vibrations.
Avoid operating temperatures below -10°C or above +50°C. Do not expose the radio sets to direct
sunlight for a prolonged period (e.g. rear window shelf in the vehicle). Do not employ the radio
sets in the rain: however, if the radio set has become wet, switch it off immediately, take out the
battery pack/the batteries and dry it by means of a soft, lint-free cloth. Only employ the radio set, if
it is completely dry.
Never throw the battery packs/batteries into the re! Never short-out the contacts of the battery
pack!
Important information
stabo freecomm 450 is a PMR 446-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,
HR, HU, NL, NO, PL, PT, SE, 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 8 specied channels (446 MHz). Within the radius of
reach (max. 5 km) 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 condential!
The range is a function of many factors. Apart from the statutory transmitting power other fac-
tors 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 (i.e. unobstructed view, e.g. in the open country, during sail-
ing or paragliding) PMR 446 radio sets have a maximum reach of 5 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 metres or less.

Important provisions for the operation!
The battery packs included in the scope of delivery have already been inserted correctly into the
radio sets!
Before the commissioning of the radio sets the battery packs have to be charged (charging time
approx. 12to 14hours).
Note:Beforetherstchargingyouhavetopullthecontactprotectionstripoutofthe
radio sets in direction of the arrow!
Charging of the battery packs
The charging current of this battery charger is adjusted to approx. 50 mA to 100 mA, the
charging time thus depends on whether you want to charge one or two battery packs and on
the state of charge and the capacity of the battery pack. Recharging of partly discharged battery
packs is basically possible; however, it reduces their lifetime.
The tabletop charger does not switch off automatically. Be sure to terminate the charging in time
in order to avoid overcharging of the battery pack, as repeated overcharging also reduces their
lifetime.
Maximum charging times:
With completely discharged battery packs with a capacity of 700 mAh the two battery packs are
fully charged after 12–14hours. If you want to recharge two half-full battery packs, the charging
time is only 6–7hours. If you only put one radio set into the charger for charging, the charging
current doubles from approx. 50 mA to approx. 100 mA; thus the charging times are reduced by
half!
Charging of the battery pack in the radio set:
1. Plug the power supply unit into a 230 V socket.
2. Connect the power supply unit to the charger.
3. Switch off the radio sets.
4. Place the radio sets into the charging shaft.
The control lamps on the charger emit red light, the battery packs are now being charged
(charging times please see above).
Safety instructions for the charger
The double tabletop charger must only be used for the charging of the NiMH battery packs that
are included in the scope of delivery!
Do not place radio sets that are equipped with batteries (not rechargeable), into the charger!

10
There is explosion hazard!
The charger must only be operated with the delivered power supply unit. Do not abuse it as DC
voltage source for other applications.
Prevent small metal parts from penetrating into the charger.
Do not disassemble neither the power supply unit nor the charger.
Disconnect the device from the mains if you do not use it.
Never short-out the contacts of the battery pack!
Make sure that the radio sets are switched off during charging.
Only use the charger in closed rooms. Protect it from humidity, dust, heat and strong vibrations.
Removing/inserting the battery pack
Remove the battery packs, if you do not use your radio sets for
a prolonged period! Ensure the correct polarity when reinserting
the battery packs (the white indicating label is visible, the arrow
points upwards)!
Opening/closing the battery case
Take off the belt clip! Unlock the safety catch at the notch (see gure 1),
slightly lift the battery cover and pull it downwards.
Slide the cover on the housing and lock the safety catch.
Operation with batteries
Your radio sets can also be operated with three micro-batteries each (type: AAA, LR03).
It is essential to ensure the indicated polarity when inserting them into the battery case
(see gure 2)!
In case of a battery change you always have to exchange all batteries. Do not mix different
battery types, batteries with different capacities or batteries and rechargeable battery cells!
Do not try to charge a radio set that is equipped with batteries in the charger! There is explosion
hazard!
Remove the batteries, if you do not use your devices for a prolonged period!
Information on disposal of battery packs/batteries
Used up battery packs and batteries are not to be thrown into the domestic waste. Be sure to
observe the national disposal regulations and dispose used up battery packs/batteries (only if
completely discharged) with the corresponding collecting points.
