Starting & Stopping
To turn ‘ON’ Cantar, set the [MainSelector] to STOP, press
the [batt L] or [batt R] button for a couple of seconds. The
rectangular screen lights up to confirm that Cantar is pow-
ered. On the left circular screen, the ‘three-platter’ icon
blinks for 3 to 5 seconds, the time it takes the disk to wake
up; it is surrounded by the icons of the currently routed
tracks. The rectangular screen displays batt-L and batt-R
voltages, plus the system day and time.
To shut down Cantar, set the [MainSelector] to STOP, main-
tain pressure on the blue [shift] button and [batt L] or [batt R]
until '
AU REVOIR
'
is displayed. As a safety measure, if you
are not in STOP, nothing happens.
Reminder:
while in STOP, internal HDD sleeping, the current
drain is a mere 270mA. To keep the internal sync-clock run-
ning, do NOT turn ‘OFF’ Cantar during the workday.
Twin battery safety
Cantar’s low power consumption electronics offer the longest
operating time of all portable eight track audio recorders.
With a single set of on-board Li-Ion batteries, the eighteen
hour Cantar outperforms all other recorders. And with the twin
battery system you will never be taken by surprise.
While
working on a cart from a mains power supply, leave a
battery onboard and activate both inputs:
the battery will
buffer possible mains power problems or the power cord
being accidently disconnected. To avoid charging spikes,
the battery which remains on-board is not charged, just not
discharged while Cantar is connected to mains power.
Mains power supply
Only use a low ripple, 14V max, power supply able to sustain
a 4A surge at Cantar's start-up. If it is not able to deliver the
surge current, plug a NiMH (12V) battery on one side and con-
nect the power supply (14v) to the other. Activate both inputs:
the battery will supply the surge and then will be off duty thanks
to the power supply higher voltage.
NEVER
use a battery
charger, its idle voltage can go up to 24V; a Cantar killer.
Voltage
Minimum:
when the active battery drops 300mv below the
operator entered Batt Alert level, both inputs are put on-duty.
This allows the simultaneous use of a 12.5V NiMH battery
with alert level set to 10.5V, and a 14.4V Li-Ion battery with
alert level set to 12.4V (see TECHSET.14-15, p.33); alert
level reached, a two beep alarm is sent to the headphones;
the rectangular screen displays BATT LEFT (RIGHT) LOW.
While in REC, both batteries are automatically put on duty,
in case you unplug one by mistake.
Maximum:
16.6V is the maximum voltage which can be
applied to Cantar, including the Firewire socket. No prob-
lem with Mac laptops and PCs, they deliver a safe 12V.
Never connect MAC G3/5 desktops delivering 30V on
the Firewire socket,
extract the HDD from Cantar and con-
nect it directly to the Gs (it can sustain up to 40V).
Battery check
In TEST, [jog] to display the battery voltage. It also
appears in all positions whenever you press the [batt L] or
[batt R] button. Pressing a battery button for more than two
seconds puts the battery on-duty.
Power Consumption

Lithium-Ion batteries
The 14.8V/4.2Ah Aaton Li-Ion R-Cells are more powerful and
lighter than their NiMH equivalent (61Wh vs 45Wh, and 560gr
vs 695gr). To avoid their destruction by NiMH chargers, the XLR 4
pin-4 is protected by an 80V reverse voltage diode; pin-3 is directly
connected to the cells.
•
Charger LED status:
red/orange,
two hour charge to 85%
capacity;
amber,
three hour top-up;
green,
charged.
Before con-
necting a battery, reset the Mascott charger 9940 (Li 4-cell 2A
@14.8V) by turning it ‘OFF’ for 4sec.
• Supply pin-out: +Batt current is either flowing through the pin-4
diode to film cameras and Cantars under #268, or through pin-3
to Cantars having an XLR 4 socket with pins 3&4 tied together.
IMPORTANT NOTICE
• Flight rules:
"NO Lithium-Ion batteries in stowed luggage. Under
8gr of lithium content, carry on as many as you want within size and
weight limits. Between 8gr & 25gr, carry on no more than two bat-
teries with a total lithium content between them of 25gr max."
At 5.8gr, Aaton R-Cells fall within the first category.
