Who-has-catled call (Call Queue)
This is a convenient facility which is useful to check who has called you and eventually call back
him/her. First of all please note that your HP125/HP425 has a sort of buffer reception memory which
This buffer memory is displayed similarly to the address book and is a FIFO (First In First Out) type: it
means that the 10 stored address (the oldest received call) is the first which will be deleted after the
11‘" received call in order to make room for it
In the over stated example the 1"t received call came from Peter, so it will be deleted from the call
queue as soon as a new call will be received. All the other addresses (Names with associated IDs) will

Battery Packs
lntomrltion on rechargeable batteries
- When the battery pack is new it doesn't provide 100% of its emciancm it means that it might be
discharged earlier. To reach the full battery life you have to "run-in" the battery with at least 34
deep charging/damaging cycles, alter that it will reach its maximum capacity. Please see
'Proper|y charge of battery packs’ for further details.
- Should you properly use the battery pack you will obtain at least 400 charging/discharging
cycles (300 with the optional rapid charger). The battery duty will progressively reduce after 213
or its life (approx),
0 Rechargeable battery packs lose their charge with the time if left unused (self discharge); this
is normal. A NiMH (Nickel Metal Hydrate) battery can reduce 10 to 20% or its stored energy in
few days.
Properly charm of bin-hr packs
1) Ensure that the radio is switched off. otherwise switch it off by holding the a) (power) key pressed
(release it otter the radio is witched off).
2) Insert the radio into the cradle as explained In the paragraph “Charging the battery pack'
3) Wait the necessary time to provide a full charge. if the pack isn't completety disotte so you will
need less than 8 hours. Evaluate the time by using the battery level indicator and... the
common sense.

is? When possible, charge the battery when it is fully discharged or, at least, you have used it for the
major part of its duty; otherwise the battery‘s duty could be temporarily reduced. Please see the
paragraph “Memory effect”.

temporarily reduced Please see the paragraph “Memory effect’i
"MM
The supplied NiMH (Nickel Metal Hydrate) battery pack is made with a more advanced technology than
normal NiCd (Nickel Cadmium) battery. For this reason it is virtually free of what is called “memory
street”, which streets NiCd batteries. Memory effect is a temporary capmity reduction which reduces
the battery duty. Memory effect may oomr just if you raga/any charge the battery when you haven't
disdrarged it at least at 50-70%. Memory effect can be easily avoided by fol|0wing these simple rules:
Page. 35
HP125/HP425 User manual
- When possible charge battery packs only when they are completely discharged, La. when the
battery icon has no bars inside.
- Don’t remove the battery from the charger before the namary time to provide a full charge.
. Provide at least two deep charge/discharge cycles per month.
- The best way to avoid memory sited is to use two battery packs and attamate their use with
the radio. This will allow you to keep on your transceivers operation by replacing the battery
pack just when it's fully discharged and use the spare (charged) one. At the end of your
working day you will oharge the discharged pack for 8 hours.
Erasing mortuary moot
Memory effect can be easily erased just by applying 34 deeper charge/discharge cycles:
1) Use the battery fitted in the radio and wait till the radio switches off. Don't stop when the last battery
bar disappears from the m icon, wait till the LCD completely disappears.
2) Wait at least one hour and then try to switch on the radio by pressing the CD button: you will note
that some energy has restored in the battery, because the radio can be switched on.
3) Leave the radio in RX until the radio switches off again.
4) Repeat steps 2) and 3) three times.
5) Fully charge the battery for 9 hours and check the battery duty. If some memory etieot still exist 90
back to step 1.
if the battery duty doesn’t improve alter three of the over stated cyclies, it means that your beflery
pack is faulty or has reached the end of lilo (please see 'lnibrmatrfon on rechargeable batteries).
In this case please ask your dealer to provide a new battery pack.
