MIDLAND GB1 is an extremely compact PMR446 mobile transceiver desi-
gned for mounting in modern vehicles with limited space. GB1 is free use
in almost all European countries.

GB1 instruction guide | 3
Content of the packaging
• MIDLAND GB1 transceiver
• Mounting bracket
• Antenna with cable
• Microphone
• Microphone holder
• Screws
• Cigarette lighter power cable
Coverage/range
The maximum range depends on terrain condition and is obtained du-
ring use in an open space.
The only limitation to maximum possible range are environmental fac-
tors such as blockage caused by trees, buildings, or other obstructions.
Inside a car or a metallic constructions, the range can be reduced. Nor-
mally the coverage in the city, with buildings or other obstructions is
about 1 or 2 Km. In open space but with obstructions like trees, leaves
or houses the maximum possible range is about 4-6 Km. In open space,
without obstructions and in sight, like for example in mountain, the co-
verage can be more than 12 Km.
Warnings
Do not open the radio for any reason! The radio’s precision mechanics
and electronics require experience and specialized equipment; for the
same reason, the radio should under no circumstances be realigned as
it has already been calibrated for maximum performance. Unauthorized
opening of the transceiver will void the warranty.

INFORMAZIONE AGLI UTENTI: Ai sensi dell’art. 13 del decreto legislativo
25 luglio 2005, n.151 “Attuazione delle Direttive 2002/95/CE, 2002/96/CE
e 2003/108/CE, relative alla riduzione dell’uso di sostanze pericolose nel-
le apparecchiature elettriche ed elettroniche, nonché allo smaltimento
dei rifiuti”. Il simbolo del cassonetto barrato riportato sull’apparecchia-
tura indica che il prodotto alla fine della propria vita utile deve essere
raccolto separatamente dagli altri rifiuti. L’utente dovrà, pertanto, confe-
rire l’apparecchiatura giunta a fine vita agli idonei centri di raccolta diffe-
renziata dei rifiuti elettronici ed elettrotecnici, oppure riconsegnarla al ri-
venditore al momento dell’acquisto di una nuova apparecchiatura di tipo
equivalente, in ragione di uno a uno. L’adeguata raccolta differenziata per
l’avvio successivo dell’apparecchiatura dismessa al riciclaggio, al tratta-
mento e allo smaltimento ambientalmente compatibile contribuisce ad
evitare possibili effetti negativi sull’ambiente e sulla salute e favorisce il
riciclo dei materiali di cui è composta l’apparecchiatura. Lo smaltimento
abusivo del prodotto da parte dell’utente comporta l’applicazione delle
sanzioni amministrative di cui al dlgs. n.22/1997 (articolo 50 e seguenti
del dlgs. n.22/1997).
All articles displaying this symbol on the body, packaging or instruction
manual of same, must not be thrown away into normal disposal bins but
brought to specialised waste disposal centres. Here, the various materials
will be divided by characteristics and recycles, thus making an important
contribution to environmental protection.

16 | GB1 instruction guide
Alle Artikel, die auf der Verpackung oder der Gebrauchanweisung die-
ses Symbol tragen, dürfen nicht in den normalen Mülltonnen entsorgt
werden, sondern müssen an gesonderten Sammelstellen abgegeben
werden. Dort werden die Materialien entsprechend ihrer Eigenschaften
getrennt und, um einen Beitrag zum Umweltschutz zu liefern, wieder-
verwertet.
Todos los artículos que exhiban este símbolo en el cuerpo del producto,
en el embalaje o en el manual de instrucciones del mismo, no deben ser
desechados junto a los residuos urbanos normales sino que deben ser
depositados en los centros de recogida especializados. En estos centros,
los materiales se dividirán en base a sus características y serán reciclados,
para así poder contribuir de manera importante a la protección y conser-
vación del medio ambiente.
Tous les articles présentant ce symbole sur le corps, l’emballage ou le ma-
nuel d’utilisation de celui-ci ne doivent pas être jetés dans des poubelles
normales mais être amenés dans des centres de traitement spécialisés.
Là, les différents matériaux seront séparés par caractéristiques et recyclés,
permettant ainsi de contribuer à la protection de l’environnement.
Όλα τα προϊόντα στα οποία εμφανίζεται το ακόλουθο σύμβολο στο σώμα,
τη συσκευασία ή το εγχειρίδιο χρήσης τους, δεν πρέπει να εναποθέτονται
στους κοινούς κάδους απορριμάτων αλλά να προσκομίζονται στα ειδικά
κέντρα αποκομιδής. Εκεί, τα διάφορα υλικά θα πρέπει να διαχωρίζονται
ανάλογα με τα χαρακτηριστικά και τα ανακυκλούμενα υκλικά,
