c. Submission of installation drawings

When line use is to begin on or after November 20, 2008
Please submit a floor plan that clearly shows where you wish to have lines installed (access locations for booths, display corners, and rooms).
Please understand that, if you do not submit this drawing, construction may not be completed by the time your exhibit begins. Please attach the drawing to each application form (using A4-sized paper). Although any format can be used, please clearly indicate the locations of line access points on your booth floor plan.

d. Billing and completion of payment and application

Approximately one week after receiving your provisional application, we will send to you a bill showing a monetary amount that is attained by calculating the total usage fees for temporary line services and consumption tax. Please send this amount by bank transfer to the account provided on the billing statement. You need to pay a bank transfer fee when you transfer money. After payment is received, we will issue a receipt to you. Your application will then be considered finalized.
It should be noted that if your billing is to include an amount that corresponds to actual use (calling charges, etc.), we will send to you an additional billing statement that covers such charges approximately two weeks after the end of your exhibit. Furthermore, if the user of communication line services is the organizer of an event, the following procedure may be used: Application → Use → Post-event billing based on actual use → Payment.
(In this case, the organizer and the billed party must be the same.)
You can use the transfer statement issued by a bank as a receipt of your payment when you pay the fee by bank remittance. Contact us if you need a receipt from us.

e. Construction and installation

If you will use communication lines within an exhibition hall, service will be scheduled to begin at 2:00 P.M. (completion of construction) on the day prior to the opening of your exhibit. If you will use the lines inside a meeting room, please inquire about the day service will begin beforehand.
We will provide telephones and modular jacks for the locations you designated in the installation drawings that you submitted in step c. However, please be aware that how booths are set up, the number of lines needed for the entire exhibition hall, etc., may affect the time when we can supply these items.

As the user, please set up your booth by taking care not to break any cables, damage loaned devices, etc. You will be billed additionally for the full cost of any cables that must be re-laid, damaged devices, etc., as well as for re-construction that becomes necessary due to major discrepancies with locations noted on the drawings you submitted. Also, please note that no cancellations will be accepted after construction and installation work has been completed.

f. Demolition

When the event has concluded, we will remove communication lines and check exhibit conditions. At this time, we will ask you to remove any booth decorations, being sure not to break any cables or damage loaned devices.
