Welcome to your new VEO 4.0. The VEO 4.0 is an easy to use dive computer utilizing a two button interface. Divers may choose between three modes of functionality consisting of Dive, Gauge, and Free Modes. Though the VEO 4.0 is easy to use, you will get the most out of your new VEO 4.0 if you take some time to familiarize yourself with its displays and operation.

Page 25: Algorithm
VEO 4.0 OPERATING MANUAL 5. ALGORITHM This feature allows the choice of using the Z+ or DSAT algorithms, for nitrogen and oxygen calculations. See p. 13 for further Dual Algorithm details. NOTE: Changing the algorithm is blocked during 24 hours after Dive Mode dives unless Desat time de- creases to 0:00.
Page 26: Bluetooth (Bluetooth Communication)
Bluetooth is initiating. When Bluetooth is turned on it will operate in sniffing mode (search- ing for compatible devices) while on the surface and the Veo 4.0 is not in Standby Mode. Communication with your Veo 4.0 must be initiated with your mobile device using Diverlog+ software.
Page 27: Sampling Rate
9. SAMPLING RATE The Sample Rate controls how frequently the Veo 4.0 stores a data snapshot for Diverlog + Download during a dive. Set- ting options are 2, 15, 30, or 60 second intervals. Shorter intervals will provide a more precise record of your dives.
Page 28: Set Mode (Operation Mode)
Set Mode allows you to choose between Dive, Gauge, and Free (free diving) Modes of operation. NOTE: Once a dive is conducted in Gauge Mode, the Veo 4.0 shall operate with limited functions without any decompression or oxygen monitoring functions. A 24 hour surface interval shall be required for the unit to operate as a full function dive com- puter in Dive or Free Mode.
Page 29: Sn (Serial Number)
Veo 4.0 requires factory service. The Veo 4.0 is configured with hidden feature that clears nitrogen and oxygen calculations. This is intended for facilities using the Veo 4.0 for rental or training activities, not for general use by individual divers. The feature is hidden to prevent accidental use. If you enter the Clear Data screen by accident, you may exit without change by holding the SEL button for 2 seconds.
Page 31: Initiating A Dive
VEO 4.0 OPERATING MANUAL INITIATING A DIVE With the Veo 4.0 in Dive mode, a dive will commence upon descending to 5 ft (1.5 m) for at least 5 seconds. Below is a diagram to help you navi- gate Dive mode functions.

COMPLICATIONS The preceding information has described standard dive operations. Your new Veo 4.0 is also designed to help you to the surface in less than ideal situations. The following is a description of these situations. Take some time to familiarize yourself with these operations before diving your Veo 4.0.
Page 36: Delayed Violation 1 (Dv 1)
• The down arrow continues to flash until descending below the required Stop Depth, then the full stop graphic will be on solid. • If the DV1 status is ignored, the Veo 4.0 will enter DV1 Surface mode for 5 minutes upon surfacing from the dive. The down arrow, Decompres- sion Stop depth/time, and Surface Time will be displayed.
Page 37: Violation Gauge Mode During A Dive
Deco is activated during a dive in Free mode, described later. Operation would then continue in VGM during the remainder of that dive and for 24 hours after surfacing. VGM turns the Veo 4.0 into a digital instrument without any decompression or oxygen related calculations or displays. Upon activation of VGM, the audible alarm will sound and the alarm LED will flash.

INITIATING A DIVE With the Veo 4.0 in Gauge Mode, a dive will commence upon descending to 5 ft (1.5 m) for longer than 5 seconds. Below is a diagram to help you navigate Gauge Dive Mode functions. The dive will end and revert to Surface Mode upon ascent to 3 ft (0.9 m) of depth for at least 1 second.
Page 42: Gauge Dive Main/Alt 1
VEO 4.0 OPERATING MANUAL GAUGE DIVE MAIN/ALT 1 This is the Main Dive screen or the Alt 1 screen if the Timer function is added to the Main screen. This screen provides basic information including depth, dive time, and ascent rate during the dive.
Page 43: Delayed Violation 3 (Dv3)
The max depth will also be represented by dashes. * The maximum functional depth (330 ft / 100 m) is the depth at which the Veo 4.0 can properly perform calculations or provide accurate display information.
Page 45: Free Dive Mode Details
• The mathematical models currently used in the Veo 4.0 are based on no decompression/decompression multilevel repetitive dive schedules. • These algorithms do not take into account the physiological changes associated with the high pressures that competitive type free diving can expose a diver to.
Page 46: On The Surface Before A Dive
VEO 4.0 OPERATING MANUAL ON THE SURFACE BEFORE A DIVE There are two Free Surface Main screens. The first screen displays when no dives have been made or greater than one minute after surfacing. The second screen displays only during the first minute after a dive.
