Safety Precautions
Please read these safety precautions carefully before using your meter. This will help you to avoid damaging the product and prevent personal injury.
This symbol identifies important warnings which should be read
in any case before initial startup of your GOSSEN product.
Warnings
In the event of malfunctioning, switch the meter off immediately.
If the event that smoke develops or unusual odors become apparent, which are caused by either the meter or the power pack,
disconnect from mains power immediately and remove the rechargeable battery from the device in order to prevent possible fire.
Continuing to operate the meter or the power pack after such malfunctions have occurred may result in severe injury.
Please contact your local dealer or GOSSEN Service in order to eliminate malfunctioning. If you bring or send the meter in for repairs,
make sure that the rechargeable battery has first been removed.
Do not use the meter in proximity to flammable gases.
Electronic devices should never be used in proximity to flammable gases. Danger of explosion and fire is otherwise immanent.
Never hang the device from children with the carrying strap.
Danger of strangulation exists if the carrying strap is hung around the neck of a child.
Store the meter at a location which cannot be accessed by children.
The meter and its accessories include parts which can be swallowed. Make sure that these parts (e.g. housing covers, rechargeable
batteries etc.) do not fall into the hands of children who might swallow them. Otherwise, danger of suffocation prevails.
Use suitable cables only.
Use included, original GOSSEN cables only for connection to external devices. GOSSEN assumes no liability if other cables are used.

Do not dismantle the meter.
Never touch any parts inside the housing. Injury may result. Do not repair the meter yourself. Repairs may only be conducted by
appropriately trained personnel. If the meter’s housing is damaged due to dropping or other external influences, remove the
rechargeable battery or power pack and contact your local dealer or GOSSEN Service for repair.
Avoid any and all contact with the liquid crystals.
If the display is damaged (e.g. broken), danger of injury due to contact with glass shards or discharge of liquid crystals exists. Make
sure that skin, eyes and mouth do not come into contact with the liquid crystals.
Be careful when handling rechargeable batteries.
Rechargeable batteries may leak or explode if handled incorrectly. Please adhere to the following safety precautions:
• Make sure that the meter is switched off before removing or inserting rechargeable batteries.
If the meter is used with a power pack, supply power must first be disconnected (pull the mains plug out of the electrical outlet).
• Only use rechargeable batteries which are recommended for this meter.
• Make sure that the rechargeable battery is correctly inserted.
• Never short-circuit rechargeable batteries, and never attempt to open a rechargeable battery.
• Do not expose rechargeable batteries to excessive heat or open fire.
• Do not expose rechargeable batteries to moisture and never immerse rechargeable batteries in water.
• After removing the rechargeable battery from the meter, close the battery compartment with the lid
(e.g. if the meter will not be used for a lengthy period of time).
• Never store rechargeable batteries together with metallic objects which might cause short-circuiting.
• Danger of leakage exists, especially in the case of empty rechargeable batteries. In order to prevent damage to the meter,
rechargeable batteries should be removed when fully depleted or in the case of lengthy periods of non-use.
• When not in use, rechargeable batteries should be stored in a cool place.
• Rechargeable batteries heat up during use and may become hot. Be careful not to burn yourself when removing rechargeable
batteries. Switch the meter off or wait until it has shut itself down, and then wait a bit longer until the rechargeable battery has
cooled down.
• Do not use rechargeable batteries which show any signs of damage such as discoloration or deformation of the housing.

1.3 Charging the Battery
Connect the included USB cable first of all to the USB port on the meter and then to the USB socket on the power pack, and then connect the power
pack to a mains outlet.
The LED in the housing top indicates the charging status of the rechargeable battery. It lights up red as long as the battery is charging, and changes to
green when the battery has been fully charged. If the meter is switched on, a symbol appears at the battery display indicating that the device is being
externally supplied with electrical power. Charging time for a fully depleted battery is about 1½ hours.
1.4 Default Settings
The MAVOSPEC BASE is shipped with default settings which, based on our own experience, fulfill the basic requirements of most users. A complete
summary of the default settings and instructions on how to adapt them to your individual requirements are included in section 4 of these operating
instructions. Entered settings are retained until they have been changed again, or until the meter is reset to its default settings as described in section 4.4.
!
When connected to a PC, the device is switched to continuous operation and is supplied with electrical power from the PC’s USB port.
The meter can be operated with or without an inserted battery when connected to a PC or to the power pack.
An additional or replacement battery (3.7 V / 890 mAh) can be purchased from GOSSEN under order number V070A.
