Freeze (“FREEZE”)
This key pauses the endoscopic live image for recording or observation.
There are two types of freeze function: “field freeze” and “frame freeze”. The
type of freeze function to start with can be set in advance in the user preset
menu. See “Freeze function” on page 225.
If the frozen image does not return to the live image, turn this
instrument OFF then ON again. Also turn the ancillary
equipment OFF then ON again by referring to the respective
instruction manual. If the image is still frozen, immediately
stop using this instrument and withdraw the endoscope
gently from the patient's body by referring to the instruction
manual of the endoscope.
1. Press the “FREEZE” key (see Figure 5.48) to freeze the endoscopic image.
2. Press the “FREEZE” key again and the frozen image returns to the live
image.
