● To perform recording in the Dual Rec mode, it is 

recommended that you start recording by making use of 
two cards with the same capacity and from the formatted 
state.

● You can combine the use of the Dual Rec mode with a 

special recording mode. While in the Dual Rec mode, you 
can also set [Rec Mode] to 

ANormalB, APre RecB, AClip 

Continuous

B, or AVariable FrameB.

● When both the slots are loaded with recordable cards, the 

Dual Rec (simultaneous recording) operation can be 
performed. If a recordable media is only loaded to one of 
the slots, you can also start recording with one card.

● In the Dual Rec mode, continuous recording by switching 

from one slot to another cannot be performed. Continuous 
recording will not be performed if a recordable media is 
loaded to a slot after recording to the other slot has 
started.

● When recording to one slot is in progress with the 

recorder set to the Dual Rec mode, loading a recordable 
media to the other slot does not enable the Dual Rec 
operation. To perform the Dual Rec operation, stop 
recording temporarily (excluding pausing recording in the 
Clip Continuous Rec mode), and start again.

● When one of the cards is accidentally removed while the 

Dual Rec operation is in progress, recording to the card in 
the other slot will continue. However, repair of the 
accidentally removed card by the recovery function may 
fail.

● If an error occurs on one of the cards in the two slots 

during recording, recording of the erroneous card stops, 
while that of the other card continues.

● Operations on clips recorded in the Dual Rec mode, such 

as clip deletion in the Media mode or appending of OK 
marks, can only be performed on the card in the selected 

slot.

Besides the normal recording mode, three special recording 
methods are available in this camera recorder. They are Pre 
Rec, Clip Continuous Rec, and Variable Frame Rec.
Select the mode from [Rec Mode] in the [Record Set] menu.

* Set using [Main Menu] B [Record Set] B [Rec Mode]. 

By setting the number of seconds in the [Pre Rec Time], you 
can start recording video and audio before actual recording 
starts based on the Pre Rec Time setting.
When starting actual recording while the camera recorder is 
in Recording Standby (STBYP) mode, you can start 
recording a few seconds earlier based on the [Pre Rec Time] 
setting.
Using Pre Rec allows you to record a complete event without 
missing the initial scenes even if you start the recording late.

* Pre Rec Time can be set to 

A5secB, A10secB, or A20secB 

in [Main Menu] B [Record Set] B [Pre Rec Time].
