26 Operating Procedure

You can select from two exposure control methods for adjusting the brightness of images appearing on the monitor. [AUTO]: The brightness is adjusted automatically so that the brightness set with the brightness adjustment switch is uniform across the monitor. [MANUAL]: The brightness set with the brightness adjustment switch is output as is without any adjustments being made.

Press K repeatedly and select a setting.

• Each press switches the item between [AUTO] and [MANUAL].

• The indicator light of the selected item will illuminate green.

If the exposure control method is set to [AUTO], you can select from two measuring methods. [AVE]: Control exposure based on the average brightness value for the whole screen. [PEAK]: Control exposure based on the maximum brightness value for the screen.

CAUTION

If the exposure control method is set to [AUTO], press d repeatedly and select a setting.

• Each press switches the item between [AVE] and [PEAK].

• The indicator light of the selected item will illuminate green.

Press e.

• Each press switches the item between [ON] and [OFF].

• When the power is turned on, the indicator light will illuminate green.

This switch sets the strength of the air supply flow of the pump. [HIGH]: Sets the air supply flow of the pump to a strong level. [LOW]: Sets the air supply flow of the pump to a weak level. The level is always set to [LOW] when the power is turned on.

Press f.

• Each press switches the item between [HIGH] and [LOW].

• When the power is turned on, the indicator light will illuminate green

WARNING

CAUTION

Exposure Control Switch

Measuring Method Switch

[AVE] should be selected for normal operation.

Pump Switch

Pump Power Switch

It must be recognized that variations in air flow (pressure and volume) for patient insufflation may exist from one manufacturer’s equipment (light source, processor and/or scope type) to another. It is, therefore, important to closely monitor the patient at all times and to aspirate excessive air to prevent overinsufflation and potential pneumatic perforation.

z Regardless of pump level setting selected, avoid delivering too much air to minimize the potential for pneumatic

perforation or barotrauma.

z Be careful not to deliver too much air.

Page 27

Operating Procedure 27

NOTE

You can manually adjust the brightness and color tone of images appearing on the monitor.

Press the a or b cc controls for [BRIGHTNESS], [BLUE], and [RED].

• Each press of a or b increases or decreases the brightness or color tone. Each press of a increases the item by one step and each press of b decreases the item by one step.

• The level of an adjusted item is indicated on the corresponding indicator of the front panel, and the value is displayed on the monitor. Note that the normal setting is 0 in case you make adjustments.

CAUTION

Adjust the white balance each time you connect a scope to the processor. You can also adjust it whenever you feel that it needs to be adjusted.

Connect the scope to the processor, turn on the processor, and set the exposure control function to [AUTO].

Press the c button to emit light from the distal end of the scope. (Refer to Figure 4.2)

Insert the distal end of the scope into the supplied white balance device and position it so that the image of the circle at the bottom of the adjuster fills the monitor.

Hold the distal end of the scope in place without moving it and press N for at least 2 seconds.

• The [W/B Proceeding] message appears on the monitor and the white balance is adjusted. After the white balance is set, [W/B OK] appears on the monitor for about 5 seconds.

Should debris on the objective lens be difficult to clean, one can temporarily

use a higher pump level setting on the video processor or light source. While doing so, simultaneously activate the air and suction control valves to minimize air insufflation. After the lens has been cleared return the air pressure to its original setting for routine use. Regardless of pump level setting selected, avoid delivering too much air.

Adjustment Switches

The exposure control method, measuring method, and brightness adjustment settings are stored in memory even if you turn off the processor.

J WATER BOTTLE CLEANING

NOTE

Water bottles should be sterilized at least on a daily basis. Like all endoscopic accessories, the water bottle assembly must be thoroughly cleaned. Failure to do so could result in incomplete or ineffective sterilization.

Q CLEANING

1 Immediately after use, the entire water bottle assembly (bottle, cap

assembly and tubing) should be washed with fresh detergent solution and dampened gauze or scrub brush. Complete immersion in a detergent solution should be used for soiled items. Internal surfaces of the water bottle assembly may be exposed to the detergent by injecting the detergent into the air pipe stem (opposite the A/W-DRAIN lever on the water bottle cap) using a syringe. The A/W-DRAIN lever should be set to the A/W position to ensure contact with all internal tubes.

2 Ultrasonic cleaning of the entire water bottle assembly is

recommended to access difficult to reach areas. Use an operating frequency of 44 kHz ± 6% for a period at least 5 minutes.

3 After washing with the cleaning solution, all surface areas of the

water bottle assembly should be thoroughly rinsed and dried. Use gauze or lint-free cloth to wipe dry most surfaces. Compressed air and 70-90% ethyl or isopropyl alcohol may be used to facilitate drying of hard to reach areas.

Q STERILIZATION

Before any attempt has been made to sterilize the water bottle assembly, ensure that the cleaning process above has been completed.

CAUTION

(1) STEAM STERILIZATION

The OS-H4 water bottle assembly has been designed to withstand high-pressure steam sterilization procedures. Use the parameters below:

Sterilizer Type : Prevacuum Temperature : 132 ~ 137°C (270 ~ 279°F)

Time : 5 - 18 minutes During steam sterilization, ensure that the cap and tubing section have been removed from the water bottle container. Make sure that the drain lever on the water bottle cap is set at A/W position (upright).

Care and Storage of the Water Bottle Set

Take care in handling the water bottle. Do NOT carry the water bottle by the Air/Water connector or Air/Water hose. When the cap assembly has been separated from the bottle, be careful in handling the water feeding stem.

z Use only the type of packaging material and package configuration as recommended by the manufacturer of the

sterilizer.

z The sterilization parameters are only valid with sterilization equipment that is properly maintained and calibrated. Use

appropriate heat process indicators and/or biological monitors as recommended by the manufacturer of the sterilizer.

Portable and mobile RF communications equipment should be used no closet to any part of the EPK-p, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter.

Recommended separation distance

d = 1.2 d = 1.2 80 MHz to 800 MHz d = 2.3 800 MHz to 2.5 GHz

where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m).

Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range.

Interference may occur in the vicinity of equipment marked with the following symbol:

NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies. NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and

reflection from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the EPK-p is used exceeds the applicable RF compliance level above, the EPK-p should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary such as reorienting or relocating the EPK-p.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Guidance and manufacturer’s declaration-electromagnetic immunity

The EPK-p is intended for use in the electromagnetic environment specified below. The customer or the user of the EPK-p should assure that it is used in such an environment.
