Electronic time recorder ER-110S IV, white, AC power compatible, compact size. - Model Name: ER-110S IV - Color: White - Size: 20cm x 15cm x 10cm - Power Supply: AC power Thank you for viewing! I've been using this time recorder for many years. Due to a reduction in business, I'm letting it go! Operation confirmed! I've been using this type for a long time. When it ran out, I could only buy it used, But, maybe it's not the era of time recorders, because they're expensive! They still cost around 11,000 yen! I prefer quick transactions, so I'm offering it at the lowest price! If you find a similar product with similar conditions that is cheaper than this, please let me know. I will adjust the price! Since there is no instruction manual, I would search online when I didn't understand something, and I would look at the electronic manual! *Time cards are not included! (I used them all up) Please comment if you have any questions! Thank you. ꒰。•◡-。꒱°・*:.。.☆
