VS-SGE20LA Wireless TV Doorphone Panasonic

I purchased this item but haven't used it, so I'm selling it.
It was purchased last summer.

The following is a copy of the product description.
Monitor Main Unit [VL-MGE20] Size: 123×80×24.5mm (excluding protrusions) / Weight: Approx. 150g (including battery pack) / Power Supply: Dedicated Nickel-Hydrogen Battery (Part Number: KX-FAN57) (DC 2.4 V) (630 mAh) / Operating Conditions: (Ambient Temperature) 0℃ to +40℃, (Humidity) 90% or less / Screen Display: 2.7-inch Color LCD Display / Exterior Material: Flame-retardant ABS Resin / Wireless Communication Method: 1.9GHz TDMA-WB
[Features] This is a wireless video intercom system that is easy to install without wiring work. The battery life of the wireless door station has been doubled (compared to VL-SGD10L (manufactured in 2016)), and it can be used for up to 2 years (using 6 Panasonic rechargeable eneloop high-end model batteries). It is equipped with an automatic recording function that can record up to 100 visitor images while you are away, with 3 consecutive images per visitor (approximately every 0.5 seconds) on the wireless monitor main unit. This is convenient as you can check them on the monitor screen after returning home.
