2.5 Radio Preparation, First Time Battery Charging
The radio transceiver comes with a 17.4 V, 1,800 mAH Lithium
Polymer Rechargeable battery. Charge the battery for the first
time between 11 and 14 hours before use, even if the green
LED indicator lights up before this time has elapsed. T
Charger Indicator Status
The charger has 3 LED status indicator lights.
Red: The battery is charging.
Green: -AC Power is connected. (no battery inserted)
-There is no battery installed.
-Battery is fully charged.
Flashing Red: Battery Failure, cannot charge battery.
Any Color, Dim LED:
The battery is damaged and may not be charged.
The charger may be used to charge either the radio with
Battery installed or battery alone.
For subsequent charges, charge until the Green LED
appears.

OTHER NOTES:

(i) Prolonged charging may reduce battery life.
(ii) Do not use unapproved battery chargers: Infinity batteries
and chargers form an integrated charging system.
(iii) The radio has a built-in battery gauge. When a single bar
appears or there is no bar, the bat-
tery needs recharging.
(iv) Never disassemble the battery.
(v) Do not throw into a fire or expose
or short circuit the connections.
(vi) Lithium batteries may be
recycled. Do not dispose of as
garbage.
(vii) Do not charge battery in a hazardous location
(viii) Do not short circuit the terminals.

About dPMR digital Private Mobile Radio 6.25 kHz Technology
Since the beginning of PMR radio, there has been a constant juggl-
ing act between available spectrum and channel size. As filter and
modulation technology has advanced the channel size has progres-
sively reduced, 100 kHz, then 50, followed by 25 and then the 12.5
kHz we have known for the last twenty or so years. Add to that the
current policy of spectrum pricing and it becomes clear that a new
advance was needed to make the most efficient and economical
use of this scarce resource.
Traditionally PMR has always operated with FDMA technology as
that has offered the best flexibility to users. The initial plan for Euro-
pean standardization was based on 2-slot TDMA technology as sev-
eral of the major PMR players have proffered that 6.25 kHz FDMA
was simply not possible. Research by Icom and Kenwood however
showed that 6.25 kHz FDMA was a practical proposition and they
entered into a joint agreement to develop the technology further.
This new digital 6.25 kHz FDMA idea was taken up by ETSI (the
European Telecommunications Standards Institute) and developed
into a European Standard. dPMR became an open, non-proprietary
EU standard and was published under the reference TS 102 490
(License-free) and TS 102 658 (Licensed).
Your K-911 radio operates in Analog as well as in both dPMR digi-
tal conventional and digital trunking modes. To enable backwards
compatibility, they also operate in 25 kHz and 12.5 kHz channel
bandwidths. Backwards compatibility to analog only radios enables
a planned migration path to "digital" with existing radios operating
analog only and new radios operating analog and digital as soon as
industry standards and norms evolve.
Therefore your radio is dPMR ready. Functions etc. are all
software defined by the programming software.
