1. GENERAL INFORMATION AND SAFETY
RECOMMENDATIONS
The purpose of this manual is to present every type of the battery charger for
PUMA T2 hand-held radio terminals and to supply a relative technical-functional
description.
1.1 AUDIENCE
This manual is thought as a reference guide for all techincal personnel. Thus it is
meant for the following people:
•Operator, in order to have a deeper knowledge of the equipment and of its
use.
•Maintenance technical personnel, in order to have a general vision of the
equipment, of its general use and its technical characteristics.
1.2 MANUAL CONTENT
The documentation present in this technical manual is organized as follows:
•Sec. 1 – General overview of the equipment and safety rules.
•Sec. 2 – Description of the TETRA Network.
•Sec. 3 – It is described in particular the internal structure of the equipment by
showing the block diagrams of the boards it is composed of.
•Sec. 4 – It gives the necessary directions to make a correct installation.
•Sec. 5 – It gives the directions to be periodically followed for the equipment’s
maintenance.
•Sec. 6 – It gives the directions to be followed to locate a fault in case of
equipment’s troubleshooting.

1.3 PUMA T2 BATTERY CHARGER OVERVIEW
The desktop battery charger is meant for indoor environments. The battery charger
is supplied by either 230 V or 115 V, therefore its location must ensure an easy
and safe access to a wall plug that is the mains sectioning device.
The battery charger is available in the following versions:
•BCP2-850
•BCP6-850
•BCU2-1500
•BCU2-1500/B
•BCU6-750
The overview of the battery charger goes on analyzing the equipment in general;
the differences among the five models will be considered in detail later.
On the battery charger shown in fig. 1.1, you can see the charging slots (1 and 2).
In every charging slot it is recommended to fit only a battery disconnected from the
PUMA T2 hand-held radio terminal. When inserting the PUMA T2 unit with the
battery pack, the plastic separating septum (3) must be removed from port and the
radio must be kept switched off during the whole charging process otherwise some
internal components can be damaged. A fast discharging button is on the battery
charger (6); it is to be used before recharging non Li-Ion batteries. Infact Li-Ion
batteries needn’t discharging before recharging. If you wish to discharge a battery
(NiCd, NiMH) you must insert it into the upper slot and press the corresponding
fast discharging button (S1).
The battery charger is equipped with a light signalling panel showing the charging
level of the battery; the meaning of the signalling is described in tab. 1.1

Every battery charger is provided with a an anti-tampering plate, placed on the
bottom of the equipment. There you can find the main data of the equipment and
the CE mark.
For example, the BCU2-1500 and the BCU6-750 plates in fig. 1.2 are reported.

In tab. 1.2 there are summarized the main features of the five different versions of
the battery charger; in the following paragraphs there will be pointed out the
differences.
